3. Scholarly vs. Popular Periodicals Different publications targeted to different audiences

4. Scholarly vs. Popular Periodicals Scholarly Purpose is to inform the scholarly world of original research in a given field Has a serious format Contains many graphs & charts few photos Regularly uses footnotes and bibliographies Written by scholars or researchers Popular/General Interest Purpose is to inform, entertain and/or sell to a wide audience Attractive/slick appearance Frequently uses photos and a few graphs & charts Rarely uses footnotes or bibliographies Written by staff or freelance writers

6. Searching Electronic Databases And The Web Too

7. Starting An Electronic Search Keywords Keywords are used when searching electronic databases and web search engines First step - Generate a list of words (keywords) that describes or is commonly used when discussing your topic. For example: –Ozone –Layer –Depletion –Atmosphere –Hole

8. Starting An Electronic Search Boolean Searching/Logic Boolean searching - Connecting keywords with the terms –and –not –or For example –eagles NOT football –(car or automobile) and exhaust More Terms = Fewer “Hits”

9. Searching More Than Just Keywords Phrases & Truncations To search for a phrase, use quotation marks –“survival of the fittest” Truncations allow for searching related words all at once –The * is usually used (! For Lexis-Nexis). For example: “child*” would include: child, children, childhood, childproof, etc.

10. Electronic Databases at the Mercer Library

11. Electronic Databases at MCCC In General Over 40 databases available Many contain periodical articles Not every article is available full text, abstracts (summary) is often available when full text is not Some are useful for searching specific subjects like business, art, or criminal justice. There are other useful tools like the Encyclopedia Britannica and the Oxford Dictionary

12. Electronic Databases In General Accessible at any computer on the MCCC/JKC campus network Most are available off campus, need to request a password. Can print/e-mail/download articles

13. Let’s look at a couple of databases EBSCOhost - Academic Search Premier –Broadest of the databases covering everything from science to the humanities including many scholarly journals –Not every article full text –Need Acrobat Reader for some articles N. Y. Times Historical Newspapers –Articles from 1851-2001 –All in pdf format, need you’ll Acrobat Reader –You may need to print out large articles in pieces

14. Searching the World Wide Web How can I find what I want?

15. Some things to consider when searching the web Everything is NOT on the web and may never be. No search engine covers the entire web. The quality of the information on the web varies greatly.

16. Searching the World Wide Web Search Strategy Searching the Web is much like database searching: –Put together a list of keywords describing the information you desire –Use Boolean logic (and, not, or) to better define your search, use double quotes for phrases, etc. When searching the web, also: –Consider which search engines/sites may best suit your search needs. Different search engines yield different results. –Use the search engine’s “advanced search” to select limiting parameters (language, date, domain, etc.)

17. Evaluating Web Information Is this stuff any good?

18. Evaluating Web Sites Quality varies greatly from site to site YOU are the sole evaluator of the quality of information a site provides

19. Five Evaluation Criteria 1.Accuracy - is it reliable? 2.Authority - is author qualified on subject? 3.Objectivity - is the information biased? 4.Currency - is the information “new” enough? 5.Coverage - does the info completely cover the topic? Search engines may put you out of context, go the home page or the “about us” page to help evaluate the site

20. The Bottom Line… Buyer Beware The web contains a vast amount of information… but not everything Anyone can put information on the web, hence the quality of web information varies greatly YOU will often be the only person to decide if the quality of the info you find on the web is good
