2	Outline Surfing the Web Using Socrates, Stanford’s Library Catalog Understanding the Scientific Literature Choosing and Evaluating Resources Developing Search Strategies Managing and Formatting References Doing a Sample Search on Vancomycin
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 Wikipedia http://www.wikipedia.org/ 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
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: Analytical Chemistry Sites (selected list of guides) http://library.stanford.edu/depts/swain/help/subjectguides/analytical.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.
8	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
9	Socrates – Tips for Searching Journal Titles Need full journal title for searching Socrates. To get full title from abbreviated title, use these web services: Abbreviations and Full Titles of Core Journals Covered by Chemical Abstracts http://www.cas.org/sent.html All that JAS: Journal Abbreviation Sources http://www.public.iastate.edu/~CYBERSTACKS/JAS.htm Browse rather than search by periodical title Alternate strategy: Use Combined Search tab and Sort by Title
10	Browse Periodical Title
11	Browsing by Periodical Title

14	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)

24	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 Chemistry journals have the highest average cost of all subject areas.
25	About STM Journals continued Abbreviations: Core Journals Covered by Chemical Abstracts http://www.cas.org/sent.html All that JAS: Journal Abbreviation Sources http://www.public.iastate.edu/~CYBERSTACKS/JAS.htm Quality: JCR: Journal Citation Reports (ranks prestige or “Impact Factor” of journals) http://portal.isiknowledge.com/ Access: Nearly all major STM databases have links to full-text articles. Locate where print and online journal titles are held by using: Swain’s Journal List E-Journals at Stanford Socrates, Stanford’s library catalog
26	About STM Databases Types of databases: Bibliographic Citation Structure Reaction Numeric Key Databases: Chemical Abstracts via SciFinder Scholar Web of Science
27	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 still used as web isn’t robust enough yet.
28	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
29	Major STM Databases
30	Selected Databases for Substances, Sequences & Reactions
31	SciFinder Scholar Most comprehensive database for the chemistry and chemical engineering literature. Updated daily, covers 1907 to present (w/ growing number of pre-1907). Includes over 23 million articles, 25 million compounds, 53 million sequences, and 8.7 million reactions. 9,500 serials plus patents, dissertations, technical reports, books, conferences. Only database that covers all types of documents. Also includes Medline database (1958-present). Contains cited/citing references from 1999-present. Also contains full-text links to articles. Client-software for searching Chemical Abstracts Online. http://library.stanford.edu/depts/swain/scifi/sfstop.html User-friendly yet powerful search software. Download and use on campus or at Swain. Restricted to current Stanford students, faculty, and staff. Limits on number of references you can download. Max 7 simultaneous users for campus
32	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
33	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
34	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 Have close proximity between terms Restrict keywords to title field Limit by language, doc type, pub year
35	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/bibsoftware.html This page is still under construction. ACS Style Guide – on Permanent Reserve at Swain.
