3. Using The Card Catalog The catalog is available online. Used to find books, videos and other material both in the MCCC collection and the Mercer County Public (MCL) libraries. You can have materials from MCL brought to the college. Deliveries arrive Tuesday and Friday afternoons. (DVD’s not available from MCL) You will need to have your student ID card to borrow books or use the library’s computer lab

4. Finding Books Unlike school and public libraries, MCCC uses the Library of Congress (LC) system. The LC is an alphanumeric system, for example –HE9760-9900: Air transportation [business focus] –TL500-780: aeronautics [technology focus] TL515-550: Aeronautics - History

10. Searching Electronic Databases And The Web Too

11. 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

12. 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”

13. 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 example: “child*” would include: child, children, childhood, childproof, etc.

14. Electronic Databases at the Mercer Library

15. What are electronic databases? A collection of electronically searchable information (frequently, but not limited to, periodical articles) that is accessible via the internet Access to this information is by subscription only, paid by the library. It is accessible via the internet, but it is not truly web information.

16. Electronic Databases In General Over 40 databases available Not every article is available full text though many are Abstracts (summary) is often available when full text is not

17. Electronic Databases In General Accessible at any computer on the MCCC & JKC campus network Most are available off campus, need to request a password (forms available after this class). Can print/e-mail/download articles

18. Getting to the databases Use the library quick link at mccc.edu to get to the library’s homepagemccc.edu Go to the “Online Databases & Search Engines” link (in the left column) of any of the library’s web pages.

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

21. 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.

22. 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.)

23. Evaluating Web Information Is this stuff any good?

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

25. 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

26. 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
