2	Outline Surfing the Web Understanding the Scientific Literature and the Flow of Information Developing Search Strategies Managing and Formatting References Using Books, Journals, and Databases
3	Surfing the Web Search Engines “Invisible Web” Subject Directories Content Evaluation
4	Types of Web Search Engines General Google http://www.google.com Google Scholar http://scholar.google.com Specialized ACS Journals Full-Text http://pubs.acs.org Knovel eHandbooks http://www.knovel.com National Science Digital Library http://www.nsdl.org/ Scirus http://www.scirus.com All-in-One ChemID Plus http://chem.sis.nlm.nih.gov/chemidplus/ Entrez, Life Sciences Search Engine http://www.ncbi.nlm.nih.gov/gquery/gquery.fcgi Metasearch HighWire Press Plus PubMed http://highwire.stanford.edu/cgi/search SearchPlus at LANL http://search.lanl.gov/ssplus/jsp/AdvancedSearch.jsp FlashPoint http://flashpoint.lanl.gov/
5	The “Invisible Web” The Invisible Web is made up of thousands of databases and searchable sources that contain highly targeted and valuable information, and whose content is not seen (indexed) by traditional search engines. Examples include: News sites updated frequently Subscriber only access Free but registration required Interactive pages created dynamically
6	Subject Directories Merits of using a directory instead of a search engine include: Quick access to a manageable number of pre-selected resources. An easily understood arrangement for browsing. Annotations and ratings. Independent specialized referral. Example: Swain Subject Guides http://library.stanford.edu/depts/swain/help/subjectguides/index.html
7	Checklist for Internet Quality Fitness for purpose – site serves intended purpose Content – unique, relevant Authority/Credibility – author identified, opinions or facts, sources cited, errors and quality control Timeliness/Currency – maintained, no dead links Navigation – clear logical structure Ease of Access – site busy, unavailable Design/Style – readable, use of graphics, ADA Performance – response time, browser compatibility Source for checklist: Annette Skov. Internet Quality: Separating the Wheat from the Chaff. Database Aug/Sept, 1998, p. 40.

10	Flow of Scientific Information (Source: http://www.indiana.edu/~cheminfo/acs800/structs.html)
11	Search Strategy Checklist Get overview of topic by consulting books, encyclopedias & review articles Identify search terms and select sources to search Choose what indexes to search, proximity of search terms to one another, and what terms to “stem” Do sample search, entering terms in priority order. Display full record of relevant articles to identify additional search terms
12	Refining a Search Strategy To broaden search: Only use 1-2 concepts Stem all terms Use acronyms, synonyms & related terms Allow terms to be anywhere in the same record View cited/citing references Search full-text instead of citation databases To narrow search: Use 3-4 concepts Don’t stem terms or don’t make stems too short Have close proximity between terms Restrict keywords to title field Limit by language, doc type, pub year
13	Managing & Formatting References RefWorks (http://www.refworks.com/refworks/) Stanford Libraries have site license. Use is free for all Stanford students, faculty, and staff. Web based product that you can use to Store your bibliographic references. Use Write-N-Cite with Word to put footnotes into a manuscript. Select an output “style” to format your references. For more information, please see: http://library.stanford.edu/depts/serg/services/instruction/bibsoftware/index.html
14	Socrates, Stanford’s Library Catalog http://socrates.stanford.edu Contains cataloging information for print books, journal titles, theses, conference proceedings, technical reports, etc. acquired by the Stanford Libraries Contains cataloging information for electronic journals and some eBooks, conference proceedings, and technical reports acquired by the Stanford Libraries Does NOT contain article level information published in journals
15	Socrates – Tips for Searching Journal Titles Need full journal title for searching Socrates. To get full title from abbreviated title, use these web services: All that JAS: Journal Abbreviation Sources http://www.public.iastate.edu/~CYBERSTACKS/JAS.htm Browse rather than search by periodical title
16	Socrates – Tips for Searching Titles and Subjects Searching Title identifies items that have your term in the title of a book, journal or conference proceeding. Use a database instead of Socrates to search titles of papers that were published in journals. Focused Search: Search “ideal” term as title word and view full record to see official subject terms. Broad Search: Search “Everything” to find your term in anywhere in the library catalog record (e.g. table of contents or notes)
17	About STM Journals Magazines, trade and scholarly journals Publishers: Professional societies Non-Profit Organizations Commercial publishers Educational institutions Government Formats: print & electronic Peer-reviewed vs. non-peer reviewed Types of articles: Research articles Rapid communications Review articles Access: Off-campus access instructions http://library.stanford.edu/apcproxy/index.html Nearly all databases and Socrates have links for potentially viewing full-text articles. Quality: JCR: Journal Citation Reports (ranks prestige or “Impact Factor” of journals) http://portal.isiknowledge.com Science-Technology-Medicine journals are usually expensive Open access Author’s personal web pages
18	About STM Databases Types of databases: Bibliographic Citation Structure Reaction Numeric Key Databases: Web of Science (or SciSearch) SearchPlus (SciSearch, Biosis, Engineering Index, & Inspec) SciFinder Scholar Derwent Innovations Index
19	Major STM Databases
20	Selected Databases for Substances, Sequences & Reactions
21	Web of Science “Core” Journals Only Cover 1900-, updated weekly 6,000 journals covering sciences, medicine, and engineering Cover to cover indexing of issues Unique feature is ability to see who has cited a paper Web interface http://www.isiknowledge.com Unlimited number of simultaneous users Includes link to full-text articles and Socrates
22	SearchPlus via LANL & FlashPoint SearchPlus http://search.lanl.gov/ssplus/jsp/AdvancedSearch.jsp Arts & Humanities (1975+) Social Science (1973+) SciSearch (1900+) BIOSIS (1969+) Engineering Index (1884+) INSPEC (1898+) FlashPoint http://flashpoint.lanl.gov/ SearchPlus PubMed MathSciNet

24	SciSearch via LANL – Search Tips Terms automatically stemmed (variant endings searched) Two adjacent terms are searched as a phrase Use AND between terms – terms may be anywhere in record Use <near/#> to have terms being searched closer together Ex: <near/5> terms must be within 5 words of one another Options for focusing results: Search terms only in the title Limit results to Document type = review Specify Category (e.g. Chemistry, Analytical) to limit subject areas of journals searched Limit by publication year Sort results by Times Cited to find most cited papers
25	Chemistry Databases are Large and Complex Chemistry databases are the largest ones of all the subject areas Types of searches: bibliographic, cited/citing references, structure, reaction, sequence, and numeric. Key document types: journals, patents, conferences, dissertations, monographs and reference works. Client-server technology used as web isn’t robust enough yet.
26	Chemistry Databases are Large and Complex Handbooks such as Beilstein and Gmelin, have up to 350 and 800 fields respectively, for a substance. Data entry based on a myriad of rules and formats Nomenclature Rules MFs: Hill System Order and Case Sensitivity Numeric ranges vs CAS Registry Numbers
