8 Our Goals Google 201: –Learn how Google really works. –Discover some Google secrets no one ever tells you. –Play around with some of Google’s advanced search operators. Google 301: –Discover the “core plus more” including some brand new Google tools and sites –Find out what Google has in store for us in the future Find out where to get more Google-related help and information. DO ALL OF THIS IN ENGLISH!

9 Part One: How Google REALLY Works Or, at least, how I think Google really works.

10 One Word of Warning For obvious reasons, the folks at Google would rather the Wizard of Oz stay behind the curtain, so to speak. So, what you are about to see on the next few slides are just plain guesses on my part. And, my guesses are probably completely wrong! But they’re pretty. And that’s all that matters.

11 Another Word of Warning I also need to warn you that my guesses use a little bit of algebra, but I promise it is simple algebra. –Well, there is one intimidating-looking equation, but we’ll get to that in a bit. Just remember that, in this case, X > Y > Z, and there can be different values for each variable (X 1 > X 2 … > X n.) I’ve lost you already, haven’t I?

12 How Google Works - Phrases When you search for multiple keywords, Google first searches for all of your keywords as a phrase. I think. So, if your keywords are disney fantasyland pirates, any pages on which those words appear as a phrase receive a score of X. Image source: Google Source: Google Hacks, p. 21

13 How Google Works - Adjacency Google then measures the adjacency between your keywords and gives those pages a score of Y. What does this mean in English? Well … Image source: Google Source: Google Hacks, p. 21

14 How Adjacency Works A page that says “My favorite Disney attraction, outside of Fantasyland, is Pirates of the Caribbean” will receive a higher adjacency score than a page that says “Walt Disney was a both a genius and a taskmaster. The team at WDI spent many sleepless nights designing Fantasyland. But nothing could compare to the amount of Imagineering work required to create Pirates of the Caribbean.”

15 How Google Works - Weights Then, Google measures the number of times your keywords appear on the page (the keywords’ “weights”) and gives those pages a score of Z. A page that has the word disney four times, fantasyland three times, and pirates seven times would receive a higher weights score than a page that only has those words once. Source: Google Hacks, p. 21

16 You Still With Me?

17 Putting it All Together Google takes –The phrase hits (the Xs), –The adjacency hits (the Ys), –The weights hits (the Zs), and –About 100 other secret variables Throws out everything but the top 2,000 Multiplies each remaining page’s individual score by it’s “PageRank” And, finally, displays the top 1,000 in order.

18 PageRank? There is a premise in higher education that the importance of a research paper can be judged by the number of citations the paper has from other research papers. Google simply applies this premise to the Web: the importance of a Web page can be judged by the number of hyperlinks pointing to it from other pages. Or, to put it mathematically [brace yourself – the next slide contains the intimidating-looking equation I warned you about] … Source: Google Hacks, p. 294

19 The PageRank Algorithm Where PR(A) is the PageRank of Page A PR(T1) is the PageRank of page T1 C(T1) is the number of outgoing links from the page T1 d is a damping factor in the range of 0 < d < 1, usually set to 0.85 Source: Google Hacks, p. 295

20 You Can Start Breathing Again I promise there are no more equations in this presentation. I just wanted to show you that the PageRank of a Web page is the sum of the PageRanks of all the pages linking to it divided by the number of links on each of those pages. –A page with a lot of (incoming) links to it is deemed to be more important than a page with only a few links to it. –A page with few (outgoing) links to other pages is deemed to be more important than a page with links to lots of other pages. Source: Google Hacks, p. 295

21 Part One: In Summary Google first searches for your keywords as a phrase and gives those hits a score of X. Google then searches for keyword adjacency and gives those hits a score of Y. Google then looks for keyword weights and gives those hits a score of Z. Google combines the Xs, the Ys, the Zs, and a whole bunch of unknown variables, and then weeds out all but the top 2,000 scores. Finally, Google takes the top 2,000 scores, multiplies each by their respective PageRank, and displays the top 1,000. I think.

22 Part Two: Search engine math I said “no more equations.” I didn’t say “no more MATH!”

23 Google rule #1 Be specific... because if you aren’t specific, you’ll end up with a bunch of garbage!

24 Google rule #2 Use quotes to search for phrases. “patrick crispen”

25 Google rule #2a Use dashes between words to also search for phrases. patrick-crispen Source:

26 Google rule #3 Use the + sign to require an exact match. [Well, not really.] “patrick crispen” +tourbus

27 Google rule #4 Use the - sign to exclude. “patrick crispen” -tourbus

28 Google rule #5 Combine symbols as often as possible (see rule #1). “patrick crispen” –tourbus +pepperdine

29 Part Two: In Summary 1.Be specific... because if you aren’t specific, you’ll end up with a bunch of garbage! 2.Use quotes [or dashes] to search for phrases. 3.Use the + sign to require. [Well, not really.] 4.Use the - sign to exclude. 5.Combine symbols as often as possible (see rule #1).

30 Part Three: More Stuff No One Tells You Google’s shocking secrets revealed!

31 Google’s Boolean Default is AND But there are ways to get around that.

32 Boolean Default is AND If you search for more than one keyword at a time, Google will automatically search for pages that contain ALL of your keywords. A search for disney fantasyland pirates is the same as searching for disney AND fantasyland AND pirates But, if you try to use AND on your own, Google yells at you.yells at you Source:

33 Phrases To search for phrases, just put your phrase in quotes. For example, disney fantasyland “pirates of the caribbean” –This would show you all the pages in Google’s index that contain the word disney AND the word fantasyland AND the phrase pirates of the caribbean (without the quotes) By the way, while this search is technically perfect, my choice of keywords contains a (deliberate) factual mistake. Can you spot it? Source:

34 Arr, She Blows! Pirates of the Caribbean isn’t in Fantasyland, it’s in Adventureland in Orlando and New Orleans Square in Anaheim. So searching for disney AND fantasyland AND “pirates of the caribbean” probably isn’t a good idea. Image source:

35 Boolean OR Sometimes the default AND gets in the way. That’s where OR comes in. The Boolean operator OR is always in all caps and goes between keywords. For example, an improvement over our earlier search would be disney fantasyland OR “pirates of the caribbean” –This would show you all the pages in Google’s index that contain the word disney AND the word fantasyland OR the phrase pirates of the caribbean (without the quotes) Source:

36 Three Ways to OR at Google Just type OR between keywords –disney fantasyland OR “pirates of the caribbean” Put your OR statement in parentheses –disney (fantasyland OR “pirates of the caribbean”) Use the | (“pipe”) character in place of the word OR –disney (fantasyland | “pirates of the caribbean”) All three methods yield the exact same results. Source: Google Hacks, p. 3

37 OR, She Blows! Just remember, Google’s Boolean default is AND Sometimes the default AND gets in the way. That’s where OR comes in. Image source:

38 Capitalization Does NOT Matter The old AltaVista trick of typing your keywords in lower case is no longer necessary.

39 How Insensitive! Google is not case sensitive. So, the following searches all yield exactly the same results: disney fantasyland pirates Disney Fantasyland Pirates DISNEY FANTASYLAND PIRATES DiSnEy FaNtAsYlAnD pIrAtEs Source:

40 Google Used to Have a Hard Limit of 10 Keywords Bet you didn’t know THAT! Source: Google Hacks, p. 19

41 Google’s 10 Word Limit Until recently, Google wouldn’t accept more than 10 keywords at a time. –Any keyword past 10 was simply ignored. Google now accepts up to 32 keywords. –Stick with 10. Source: Google Hacks, p. 19

42 Google Supports Stemming and Wildcard Searches! When you wish upon a *.

43 Stemming and Wildcards Wildcards are characters, usually asterisks (*), that represent other characters. For example, some search engines support a technique called “stemming.” –With stemming, you search for something like pirate* and the search engine shows you all the pages in its database that contain variants of the word pirate – pirates, pirated, etc. But, did you notice I said “some search engines?”

44 Google and Stemming Google doesn’t require a wildcard to stem. When appropriate, Google automatically searches not only for your search terms but also for words that are similar to some or all of those terms. A search for pirate life for me will also automatically include hits for –pirate’s life for me –pirates life for me –Pirated life for me You can turn off stemming with a + or quotes, but not always. Source:

45 Google and Wildcards As for wildcards, Google doesn’t offer stemming wildcards but rather offers “full-word” wildcards. For example, if you search Google for it’s +a * world, Google shows you all of the pages in its database that contain the phrase “it’s a small world” … and “it’s a nano world” … and “it’s a Linux world” … and so on. Source: Google Hacks, p. 37

46 it’s +a * world Most of the hits are phrases because that’s what Google looks for first. Oh, and I defy you to get that song out of your head! Image source:

47 Wildcards and the Word Limit Google doesn’t count wildcards toward the 32 word limit. For example, Google thinks that though * mountains divide * * oceans * wide it's * small world after all is exactly 10 words long. Source: Google Hacks, p. 19

48 Fun with Wildcards Just for grins, try searching for * * –This reportedly returns EVERYTHING in Google’s index, although I seriously doubt that. You can also use wildcards to write poetry. –Write down the first line on paper. It’s a world of laughter, a world of tears. –Find a word that rhymes with the last word. Tears > Fears –Search Google for the next line using wildcards. * * * * * * * * fears. Source: and

49 The Order of Your Keywords Matters A me life for pirate’s?

50 How Google Works When you conduct a search at Google, it searches for –Phrases, then –Adjacency, then –Weights. Because Google searches for phrases first, the order of your keywords matters. Image source: Google Source: Google Hacks, p

51 For Example A search for disney fantasyland pirates yields the same number of hits as a search for fantasyland disney pirates, but the order of those hits – especially the first 10 – is noticeably different.

52 Part Three: In Summary Google’s Boolean default is AND. Capitalization does not matter. Google has a hard limit of 32 keywords. Google supports stemming and wildcard searches. The order of your keywords matters.

53 Part Four: Advanced Search Operators Beyond plusses, minuses, ANDs, ORs, quotes, and *s

54 How Google Finds New Pages Google has special programs called spiders (a.k.a. “Google bots”) that constantly search the Internet looking for new or updated Web pages. When a spider finds a new or updated page, it reads that entire page, reports back to Google, and then visits all of the other pages to which that new page links. Image source:

55 Paging Miss Muffet When the spider reports back to Google, it doesn’t just tell Google the new or updated page’s URL. The spider also sends Google a complete copy of the entire Web page – HTML, text, images, etc. Google then adds that page and all of its content to Google’s cache.

56 So What? When you search Google, you’re actually searching Google’s cache of Web pages. And because of this, you can search for more than text or phrases in the body of a Web page. Google has some secret, advanced search operators that let you search specific parts of Web pages or specific types of information. Source: Google Hacks, p. 5

57 Advanced Operators Query modifiers filetype: intitle: inurl: site: synonyms Alternative query types cache: link: related: info: Other information needs phonebook: stocks: define: Google Calculator weather movies:

58 Query Modifiers Stuff you can add to your regular searches

59 filetype: filetype: restricts your results to files ending in ".doc" (or.xls,.ppt. etc.), and shows you only files created with the corresponding program. There can be no space between filetype: and the file extension The “dot” in the file extension –.doc – is optional. Source:

60 Google’s Official Filetypes Adobe Portable Document Format (pdf) Adobe PostScript (ps) Lotus (wk1, wk2, wk3, wk4, wk5, wki, wks, wku) Lotus WordPro (lwp) MacWrite (mw) Microsoft Excel (xls) Microsoft PowerPoint (ppt) Microsoft Word (doc) Microsoft Works (wks, wps, wdb) Microsoft Write (wri) Rich Text Format (rtf) Shockwave Flash (swf) Text (ans, txt) Source:

61 filetype:extension pirates filetype:pdf pirates -filetype:pdf

62 intitle: Using intitle: restricts the results to documents containing a particular word in its title. There can be no space between intitle: and the following word. You can also search for phrases. Just put your phrase in quotes. Source:

63 Title? Pirates of the Caribbean...

64 intitle:terms intitle:pirates pirates -intitle:”walt disney”

65 A Quick Question What would happen if I searched for intitle:walt disney (without the quotes?) Google would look for every page with the world walt in its title AND the word disney somewhere in its body. Remember, the quotes are kind of important if you want to search for phrases using intitle:

66 inurl: Using inurl: restricts the results to documents containing a particular word in its URL. There can be no space between inurl: and the following word. Source:

67 URL? A URL is a uniform resource locator, a string that uses a standard syntax to identify an access protocol, location, and identifier for a file or other Internet resource. –http://www.disney.com/http://www.disney.com/ –http://www.google.com/http://www.google.com/ –ftp://wuarchive.wustl.edu/ftp://wuarchive.wustl.edu/ –news:google.public.support.generalnews:google.public.support.general Source:

68 inurl:term inurl:disney pirates –inurl:disney

69 site: Using site: restricts the results to those websites in a domain. There can be no space between site: and the domain. Source:

70 site:domain pirates site:disney.com

71 Using site: You use site: in conjunction with another search term or phrase. pirates site:disney.com You can also use site: to exclude sites. pirates –site:disney.com You can use site: to exclude or include entire domains (and, like with filetype, the dot is optional). pirates –site:com pirates site:edu Use an OR search to include or exclude hits from multiple sites or domains.

72 Synonyms Using ~ before a keyword tells Google to search for both that keyword and its synonyms. There can be no space between ~ and the keyword. Source:

73 ~keyword pirate ~treasure

74 Alternative Query Types Stuff you can use if you want to search without using any keywords

75 cache: Using cache: shows the version of a web page that Google has in its cache. There can be no space between cache: and the URL. You can use cache: in conjunction with a keyword or phrase, but few do. Source:

76 cache:URL cache:disney.com

77 link: Using link: restricts the results to those web pages that have links to the specified URL. There can be no space between link: and the URL. Source:

78 link:URL link:disney.com

79 related: Using related: lists web pages that are "similar" to a specified web page. There can be no space between related: and the URL. Source:

80 related:URL related:disney.com

81 info: Using info: presents some information that Google has about a particular web page. There can be no space between info: and the URL. Source:

82 info:URL info:disney.com

83 Other Information Needs Did you know that Google can look up phone numbers, stock quotes, dictionary definitions, and even the answer to math problems?

84 phonebook: There are two ways to use Google’s phonebook: –Just do a regular search. –Use one of Google’s phonebook commands. Phonebook commands [in lowercase]: –phonebook: searches the entire Google phonebook. –rphonebook: searches residential listings only. –bphonebook: searches business listings only. Source:

85 How to Use the Phonebook first name (or first initial), last name, city (state is optional) first name (or first initial), last name, state first name (or first initial), last name, area code first name (or first initial), last name, zip code phone number, including area code last name, city, state last name, zip code

86 phonebook:Data phonebook:disneyland ca phonebook:(714)

87 stocks: If you begin a query with stocks: Google will treat the rest of the query terms as stock ticker symbols, and will link to a Yahoo finance page showing stock information for those symbols. Go crazy with the spaces – Google ignores them! Source:

88 stocks:Symbol1 Symbol2 … stocks: msft stocks: aapl intc msft macr

89 define: If you begin a query with define: Google will display definitions for the word or phrase that follows, if definitions are available. You don’t need quotes around your phrases. Source:

90 define:term define:pirate define:barbary coast

91 Google Calculator Simply key in what you'd like Google to compute (like 2+2 ) and then hit enter. Google’s Calculator can solve math problems involving basic arithmetic, more complicated math, units of measure and conversions, and physical constants. Source:

98 Part Five: The Rest of the 70% Behind the Google homepage

99 Home Sweet Home

100 I’m Feeling Lucky

101 “Well, Do Ya … Punk?” The “I’m Feeling Lucky” button takes you directly to the first web page Google returns for your query. You won’t see any other search results. Source:

102 Google bombing “Google bombing” is an attempt to influence a certain page’s Google ranking. If enough people create web pages that use the same anchor text to point to the same web page [for example, if several hundred web pages linked the phrase “cow poly” to you can force that page to become Google’s first hit. And “I’m Feeling Lucky” automatically takes you to that first hit.

103 Examples of Google bombs Three examples: –Failure –Great President –French Military Victories Is this Google’s fault? NO! –Google bombs AREN’T editorial statements by Google. –People are just “gaming” PageRank. –“Fixing” this would be a slippery slope.

104 Google’s “Hidden” Search Options

105 Hiding in Plain Sight To the right of the search box are three links practically no one has never noticed: –Advanced Search –Preferences –Language Tools

106 The Limitations of Advanced Search Advanced Search is a one-shot deal. –You aren’t permanently changing any of your Google settings. –“Search for this and then forget these settings the next time I come back.” With a few exceptions, the “advanced” stuff is just search engine math and advanced search operators.

107 Advanced Search: Find Results You already know how do all of these on Google Homepage’s using search engine math! The only new thing is the number of results pull-down list in the upper right corner.

108 Advanced Search: Other Options You [should] already know how to do file format, occurrences, and domain searches from the Google homepage. Most of the rest are self-explanatory.

109 Usage Rights – No Filter Aren’t filtered by license = “show me everything.” This is a default Google search.

110 Usage Rights – Reuse Filter Allow some form of reuse = “show me stuff I can reuse with restrictions.” –You must attribute the work. –You cannot use the work for commercial purposes. See 5b for more information.

111 Usage Rights – Freely Modify Can be freely modified, adapted, or built upon = “stuff I can reuse with attribution.” See dtuu3 for more information.

112 Advanced Search v. Preferences Advanced Search = “search once using these settings.” Preferences = –“Change the way Google works for me from here on out.” –Changes every Google service you use, not just search.

113 Google Preferences When you change your Google preferences, Google writes a cookie to your hard drive. Your Google preferences are “permanent” until you: –Change your preferences. –Toss your cookies. In Internet Explorer: Tools > Options > Delete Cookies In Mozilla/Firefox: Tools > Options > Privacy > Clear Cookies. –Go to The extra period at the end forces you to go to the English language version of Google. Source: Google Hacks 2 nd Ed, p. 21

114 Interface Language Interface Language lets you change the default language used to display the interface of every Google page you visit. Change the Interface Language to Chinese (Traditional), save your preferences, and watch what happens…

115

116

117 Interface Language Limitations Notice the hits are still in English. –Google doesn’t translate the hits to your default language. Yet. The only thing that’s changed is the default language of Google’s interface.

118 Using Interface Language This is great for foreign language immersion. This is also a WONDERFUL practical joke to play on a friend or colleague. –“Hey, why is Google in PIG LATIN!?” Remember, your Google preferences are “permanent” until you: –Change your preferences. –Toss your cookies. –Go to

119 Preferences: Search Language Using Preferences, you can also “permanently” force Google to search only pages written in a specific language or languages.

120 Preferences: SafeSearch Filtering Google's SafeSearch Filtering screens for sites that contain explicit sexual content and deletes them from your search results. By default, it only filters explicit images. To filter both images and text, choose “Use strict filtering.” Source:

121 SafeSearch Minuses and Plusses No filter, even Google’s, is 100% perfect. –An image search for the name of the wife of a well- known actor with SafeSearch set to moderate or strict still returns inappropriate images. Search for one of the “seven deadly words” with SafeSearch set to strict and it’s almost like searching for * * –Google does block the word. –But then Google returns way too many pages. –PageRank becomes the filter. Still, SafeSearch eliminates most inappropriate material from your searches. Source:

122 More Preferences Number of Results and Results Window are self- explanatory. Remember, your Google preferences are “permanent” until you: –Change your preferences. –Toss your cookies.

123 Wait. There’s More!

124 Language Tools Like Advanced Search, Language Tools is a one- shot deal. Use Language Tools if –You don’t want to permanently change your Interface or Search languages. –You want to translate text.

125 Google Translate Using Language Tools, you can –Translate keyed in text from one language to another. –Translate a web page’s text from one language to another. Be looking for even more robust translation tools from Google in the not-too-distant future.

126 Part Six: More Googles Data mining for fun and profit

127 Remember the Miss Muffet Slide? When Google’s spiders report back, they send Google a complete copy of everything they find – HTML, text, images, etc. Google’s web search gets all of the attention – it consumes 70% of Google’s time and energy. But why not make the other stuff the spiders find searchable as well?

128 Google’s Goal, Restated Organize the world’s information – not just web pages – and make that information universally accessible and useful Adapted from Google Factory Tour

129 Google Image Search

130 Behind the Scenes “Hey, let’s take all these cached images and make them searchable.” Two ways to get to Google Image Search –images.google.com –Go to Google [or Google Groups, Google News, Froogle, or Google Local/Google Maps] and click on the “Images” link.

131 Using Google Image Search Search engine math works here as well. Check out Advanced Image Search [to the right of the search box] for special size, filetype, and coloration options. Beware of copyright! –Google cannot grant you any rights to use the images you find for any purpose other than viewing them on the web. –To reuse the images, contact the site owner and obtain the requisite permissions.

132 Fun with Google Image Search Guess the keyword[s] I used to find this picture. There is even a free “Guess the Google” Flash game at a8zgs

133 Google Groups [Beta]

134 Behind the Scenes “Hey, let’s take the Deja News archive of over one billion Usenet postings since 1981 and make that searchable.” “And while we’re at it, let’s make it so people can create their own announcement lists, mailing lists, and public discussions as well.” Two ways to get to Google Groups –groups.google.com –Click on the “Groups” link on most Google sites.

135 Use-WHAT? Usenet –Internet-based bulletin board –Tens of thousands of theme-based, hierarchical newsgroups coving every topic imaginable –Anyone can read, post, or reply. –Huge collection of opinion, commentary, reviews, spam, and LOTS AND LOTS OF PORN!

136 How Google Groups Works Google took an archive of Usenet posts and slapped a Google search engine on top of it. –Searching Google Groups is pretty much identical to searching Google. –Check out Advanced Group Search for some Google Groups-specific search operators. Wait. There’s more.

137 The REALLY Cool Part Google Groups also lets you create your own [non-Usenet] groups. You can –Create your own private listervs. –Hold [and archive] your own online web- or -based discussions. All you need is a free Google account. –If you don’t have one already, go to groups.google.com and click on “Join.”

138

139 Signing up for a Google Account To create a Google Account: –Key in your address. –Create a password. –Key in the captcha word [the squiggly “completely automated public Turing test to tell computers and humans apart” word that appears on the page.] –Click on the “Create my account” button. –Login to your and verify your account. Then you can set up your first Google Group.

147 Google News [Beta]

148 Behind the Scenes “Hey, let’s take news articles from 4,500 online news sites and make them searchable.” Two ways to get to Google News –news.google.com –Go to Google [or Google Groups, Google News, Froogle, or Google Local/Google Maps] and click on the “News” link.

149 How Google News Works Every 15 minutes, Google gathers stories from more than 4,500 English-language news sites. A computer program automatically arranges the stories by relevance and popularity. –Sound familiar? –There are no editors or human intervention. –Google’s algorithms run everything. And if you don’t want to browse the news, you can also search the news by keyword[s.] Source:

150 Google News Tips Click on “Customize this page” to change the default layout [via a cookie.] Google News archive only goes back 30 days. –Use the regular Google for older searches. –“Copyright * The Orange County Register” Disneyland Scroll to the bottom of the Google News homepage for links to international versions of Google News.

151 Froogle [Beta]

152 Behind the Scenes “Hey, let’s take all these cached web pages on which merchants are trying to sell stuff and make those pages searchable.” Three ways to get to Froogle –froogle.com –froogle.google.com –Go to Google [or Google Groups, Google News, Froogle, or Google Local/Google Maps] and click on the “Froogle” link.

153 How Froogle Works Adapted from:

154 Google Local

155 Hey, Wait a Minute! That’s Google MAPS, not Google LOCAL! –Google Maps and Google Local merged in October “Hey, let’s take Telcontar’s NAVTEQ maps and the images we got when we bought Keyhole and make all of that searchable.” “And, while we’re at it, let’s throw in Google Local information as well.” There are several ways to get to Google Local: –maps.google.com –local.google.com –Go to Google [or Google Groups, Google News, Froogle, or Google Local/Google Maps] and click on the “Local” link.

Publishers have filed lawsuits to stop Google Print.

187 Why Cache? To understand the purpose of Google Print, you have to understand the purpose of Google’s cache. Google bots collect copies of “stuff” they find on the web: HTML, text, images, etc. That stuff is added to Google’s cache. Google indexes the cache of stuff to make it easier for you to find what you’re looking for.

188 Cache or Credit? When you search Google, Google searches through its cache looking for matches. BUT, when you click on a link, Google DOESN’T point you to their cached copy of the stuff, they point you back to the original. –Exception: The cache: search operator which only works with HTML.

189 The Fine Print Google Print caches the contents of scanned books. In response to a search query, you can browse the full text of public domain materials. BUT, for books under copyright, you can only see a few sentences on either side of the search term [for context] with links on where you can locate the book in a library or bookstore. Source:

192 How Google Print Fits In Google’s goal is to “organize the world’s information and make it universally accessible and useful.” A lot of the world’s information—like the contents of books—aren’t universally accessible and useful, especially online. Google Print lets you search for terms inside of books and then points you to real-world locations like libraries and bookstores where you can view or purchase those books.
