Spring 2012 Flow of Scientific Information Searching the Internet Library Resources 1) Define Your Topic "Piled Higher and Deeper" by Jorge Cham
www.phdcomics.com Informal distribution primary literature secondary literature tertiary literature Costs and Pricing Scientists do research and write papers and books Publishers package and sell their writings Database companies provide indexing and abstracting to help you find their writings Libraries buy books, journals, and databases to give you access to their writings distribute discover access produce Journal Pricing Database Pricing One of the databases that costs the UCLA Management Library ~$21,000 per year costs corporate clients over $100,000 per year. It's still a bargain Why does a database cost so much and what do you get for it? Quality controls on content No ads Uses a controlled vocabulary – you don’t have to think of synonyms Includes abstracts to judge the relevance of an article before you invest any more time Discovery AND access Many are subject specific “Find related articles” features Content you will only have access to if you pay or the library pays Proprietary databases; e.g.,
Travelocity; LA Times; Weather.com; Eddie Bauer The Invisible Web is 500 times bigger Google searches a billion webpages... Government websites; e.g., DOE, NASA; Bureau of the Census Web of Science, Academic Search Complete, Compendex, Environmental Sciences and Pollution Management, IEEE Xplore, etc. Unsponsored sites (i.e., professional societies) are best
Internet information on surgical risks still poor How much is inaccurate? A systematic review of patient inflammatory bowel disease information resources on the World Wide Web. Am J Gastroenterol. 2007 Sep;102(9):2070-7. Epub 2007 May 19. The median QEI score was 57 out of 107 with five Web sites scoring higher than 75 points. The median Global Quality Score was 2.0 out of 5 with five Web sites achieving scores of 4 or 5. The average reading grade level score was 11.2. The median integrity score was 3.0 out of 6. CONCLUSIONS: There is marked variation in the quality of the Web sites containing information on Crohn's disease and ulcerative colitis. Many Web sites suffered from poor quality but there were five high-scoring Web sites What is the quality of surgery-related information on the internet? Lessons learned from a standardized evaluation of 10 common operations. By Yermilov I, Chow W, Devgan L, Makary MA, Ko CY. J Am Coll Surg. 2008 Oct;207(4):580-6.

... your group Information gathered through
News (Newspaper databases)
Interdisciplinary database searching (peer reviewed journal articles)
Internet searching Technical Issues Social/Ethical Issues 2) Divide the topics among your group members Make sure the topics are approximately the same size
Make sure the sum of all the topics covers the subject ~completely
Make sure you like your topic 3) Figure Out What Kinds of Materials Will Have the Info You Need Books often take the most comprehensive view of a topic, and a recent book can point you to the recent journal literature – but books take a long time to publish.
A subject specific encyclopedia can provide an excellent overview AND give you ideas on how to divide up the topic.
Journal articles, particularly review articles, can also be broad in scope and provide in-depth information on aspects of a topic.
Newspapers give you a public interest perspective, but not in-depth science.
Government websites can be good sources of information on public interest topics Got Sources? 4) Find out if there are any useful books for your topic How do I find books? Use keywords to locate books that have relevant information.
Find one that looks appropriate and locate subject headings.
Use the subject headings to find appropriate books and refine your search. The UCLA Library Catalog http://catalog.library.ucla.edu 5) Look for Journal Articles How do I find articles? Find the right databases What's a database? A large, regularly updated file of digitized information (bibliographic records, abstracts, full-text documents, directory entries, images, statistics, etc.) related to a specific subject or field, consisting of records of uniform format organized for ease and speed of search and retrieval and managed with the aid of database management system (DBMS) software. Find the right vocabulary and use to refine search strategy.
