WAYS TO FIND MEDICAL INFORMATION ON THE INTERNET
2
WEB SEARCH TOOLS Main types of web search tools subject directories search engines meta-search engines concept categorizing search engines vertical search engines
3
THINGS TO KNOW ABOUT SUBJECT DIRECTORIES selective collections of web pages or other information sources arranged by topic, hierarchically organized by subject category assembled by teams of editors who are specialists in their subjects information retrieval is realized by browsing catalog section, sometimes the searching by keyword is offered as well
4
WHEN TO USE SUBJECT DIRECTORIES when you are just beginning your search and have only a general idea of a topic when you are interested in a broad range of information rather than a specific piece of information when you are looking for a list compiled by an expert, this helps eliminate irrelevant pages and ensures quality results
5
RECOMMENDED SUBJECT DIRECTORIES General Yahoo!

THINGS TO KNOW ABOUT SEARCH ENGINES searchable databases compiled by automated programs that continuously search the full-texts of the web pages for new and updated sites vary in method, type and amount of material indexed vary in relevancy of achieved results operate by entry of keywords
7
WHEN TO USE SEARCH ENGINES when you have a specific topic when you want to combine relevant terms when you want to retrieve a large number of web sites

9
THINGS TO KNOW ABOUT META-SEARCH ENGINES search tools of a federated search provide a single interface that enables users to search multiple search engines, indexes and databases simultaneously do not offer the same level of control over the search interface and search logic as individual search engines
10
WHEN TO USE META-SEARCH ENGINES when you want to get a general idea of what documents you can find with your terms a good strategy at the very beginning of your research

CONCEPT CATEGORIZING SEARCH ENGINES When to use concept categorizing search engines when a search is a general one and you want to learn about the component concepts of your topic when you know very little about your topic and want help in identifying its scope and content when your topic is indefinite

VERTICAL SEARCH ENGINES When to use vertical search engines when you search a specific area of the World Wide Web (WWW) – topic, geographical location, language, news, type of content (e.g. movies, images, blogs), etc.) when you have difficulty locating what you want on general, meta, or concept categorizing search engines

16
THE CONTENT OF THE WORLD WIDE WEB AND ITS ACCESSIBILITY the Surface web (Visible web) – the information you can see in almost all subject directories and information you can find using general web search engines the Deep web (Invisible web) – web content that is not part of the Surface web and is not accessible through standard search engines. It is approximately 500 times bigger than the Surface web
17
DEEP WEB CONTENT databases and online catalogues which can only be retrieved by posting a query non-text files such as images, multimedia or software, non- HTML formats such as PDF,.zip,.doc and.xls files password-protected sites

HOW TO SEARCH A TOPIC choose a topic develop a search strategy identify information sources choose a database to search search a database evaluate the information sources retrieved
20
EVALUATING SOURCES AUTHORITY (What are the author's references?) ACCURACY (Is the information reliable?) OBJECTIVITY (Does the information show bias?) CURRENCY (Is the information dated?) COVERAGE (How in-depth is the information?)
21
GENERAL TIPS FOR ONLINE SEARCHING Did you check your spelling? one small spelling error can make a huge difference Are you using the right search? author and title searches look for known items a keyword search looks for your terms anywhere in the document a subject search will look for terms in a predetermined set of subject headings. It works good if you choose the right subject term; if not, you may get zero results. It's a good idea to browse subject headings if possible.
22
LOGICAL OPERATORS Using „AND" will find all your words, but they may appear in different parts of the document and in any order (hypertension and therapy). This will narrow your search. Using „OR" will find either term and maybe both (therapy or treatment). This will broaden your search. Using „NOT" will exclude a concept (AIDS not HIV), will exclude documents containing the word „HIV" and make your search more focused.
