  1. Your Digital Library MBG 8680 Shiffman Medical Library

  2. Key to Access: Library Web Site • http://www.lib.wayne.edu/shiffman • Links to all databases, catalogs, e-books, e-journals, news • Hours, contacts, maps, services • Askmed@wayne.edu • Remote access instructions

  3. Objectives • To provide an overview of basic resources • Databases (to find articles and full text publications) • Catalog (to find journals and books) • Other tools • To increase awareness of services for you • To increase awareness of amount/pace of new information and resources

  4. Does the Library Have? • Catalog: “Imagine” • Linked from Shiffman site or http://www.lib.wayne.edu/imagine

  5. Books Paper & e-books with links Journal titles Paper & e-journals with links Other: media, microforms, databases, web sites Especially important Which library? Location? Years covered? MEDLINE abbreviation Catalog Searches

  6. Not Found in Catalog? • Visit, call or e-mail reference • Order via Interlibrary Loan (no charge) • Order as soon as possible • No charge from “other side of campus”

  7. Databases • Database is a searchable archive of structured information • Record: all information about an item • Field: information about an item is stored in a field • Bibliographic databases • Fields: author, title, journal name • Molecular biology databases • Sequence, protein translation, source organism

  8. The Question • What is insulin’s role in postprandial hypotension in diabetes patients? • Context: physician notes a severe drop in blood pressure after eating meals. Already knows insulin is suspected of playing a role.

  9. Objectives • What kind of information would you like to find? • What would it look like if you found it? • What should be included? • What should be excluded?

  10. First Steps • Write down key concepts • Expand with related terms and synonyms

  11. HEART cardiac cardiovascular DISEASE dysfunction abnormality disorder TREATMENT therapy therapeutics drug surgery Example: treatment of heart disease

  12. Time Limits? Last six months Last year Last five years Size of Retrieval? One-two relevant articles? Comprehensive? Reviews? Languages? Gender? Research type? Publication type? Next Step: Decide on Limits

  13. Choosing a Database • MEDLINE • The primary source for clinical literature • Science Citation Index/Web of Knowledge • Larger number of research and basic science journals • BIOSIS (Biological Abstracts) • Breadth of inclusion and full coverage of basic science aspects

  14. MEDLINE • Primary clinical database with increasing number of basic science journals • WSU offers MEDLINE via PubMed (free) or OVID (restricted) • OVID’s current benefit to you is link to catalog for journal information

  15. MEDLINE: Try it • Via home page or • http://pubmed.gov

  16. Results? Consider . . . • Are the articles relevant? • Too much or too little? • Are you satisfied?

  17. Insulin’s role example • CONCEPTS • Insulin • Insulin’s physiological effects • Postprandial period • Hypotension • Diabetes mellitus • Control of cardiovascular responses • Vasodilation • Cardiac output

  18. Medical Subject Headings (MeSH) Insulin Postprandial period Hypotension Vasodilation Diabetes mellitus Digestive physiology Blood pressure Eating Keywords Postprandial hypotension Low blood pressure Fall AND blood pressure meal Terms

  19. Multiple Term Combinations • Try it: • Insulin AND postprandial period • Insulin AND hypotension • Postprandial period AND hypotension • Insulin AND vasodilation • Diabetes AND hypotension • Insulin AND meal • Digestive physiology AND hypotension

  20. Building a Search • Insulin (MeSH term) • Example: insulin[mh] • Hypotension? • Example: Hypotension OR hypotensive OR (blood pressure AND fall) • Postprandial? • Example: Postprandial period[mh] OR postprandial OR digestive physiology[mh] OR eat OR food OR meal

  21. Building a Search cont’d. • Insulin’s relationship with vasodilation? • OR (insulin AND vasodilation) • Limiting to English language? • AND Eng[la] • Enter into PubMed search window

  22. AND, OR, Boolean Operators CATS DOGS Dogs OR cats: either, or, or both

  23. AND AND (Intersection) CATS DOGS Dogs and cats in the same record

  24. Test Search ((insulin[mh] AND (hypotension[mh] OR hypotensive[tw] OR (“blood pressure” AND fall)) AND (postprandial period[mh] OR postprandial[all] OR digestive physiology[mh] OR eat*[tw] OR food[tw] OR meal[tw])) OR (insulin[majr] AND vasodilation[mh]) AND eng[la])

  25. PubMed • Over 11 million citations from mid-1960s to the present (before 1960s Index Medicus) • Controlled vocabulary (MeSH) helps to focus • Provides links to “some” full-text e-articles • Updated daily • “Related articles” feature for additional citations • New e-books with links • Loansome Doc (miuwsu)

  26. PubMed • Can be time consuming because of size • Quick searches can be dangerous • MeSH terms updated annually • Includes literature from over 70 countries but has a North American bias and may omit relevant literature • Additional databases required for comprehensive basic science literature

  27. Science Citation Index • Now in Web of Knowledge with: • Social Science Citation Index • Journal Citation Reports • HighlyCited.com • Why use it?

  28. Science Citation Index • Strengths • More basic science, research journals than MEDLINE • Citation tracking (no other database has this) • Enables easy date limitations • Weaknesses • No controlled vocabulary – only keywords • Limited user interface • Maximum of 500 records per search

  29. Example: • Sandler MP, Bax JJ, Patton JA et al. • Fluorine-18-fluorodeoxyglucose cardiac imaging using a modified scintillation camera Journal of Nuclear Medicine 39(12): 2035-2043 DEC 1998

  30. Why Use Web of Knowledge? • You can find articles: • Written by an author • Written about a topic or person • That cite a particular author in the list of references • That cite a particular article in the list of references • Published within the last few days, weeks or decades • Published in a particular journals

  31. Why Use Web of Knowledge? cont’d • How often an article has been cited • The list of references from an article • Also, • Journal Citation Reports • Relative importance of a journal: “impact factor” • Journals in a discipline or sub-discipline ranked by impact factor, number of citations, other metrics

  32. BIOSIS (Biological Abstracts) • Two choices: Silver Platter or “BasicBIOSIS” in First Search • Strengths • Increased coverage of research and basic biology journals compared with MEDLINE • Good coverage of animal sciences and animal models for disease

  33. BIOSIS cont’d • Weaknesses • Has only minimal controlled vocabulary • Interface not user-friendly

  34. Try it: • Try the search in both Web of Knowledge and BIOSIS via Silver Platter (insulin AND postprandial AND (hypotension OR (blood pressure AND fall))) OR (insulin AND vasodilation)

  35. Other Publications • E-books • PubMed • Catalog • Encyclopedia of Life Sciences • E-journals

  36. E-journals • Must check catalog today under journal title or MEDLINE abbreviation • New journals added monthly • Publication far in advance of paper, including pre-publication and e-only

  37. How to Keep Up? • Current Contents (in OVID) • Current Awareness Service • Tables of content to e-mail • Sign-up information through Shiffman web site under: Services. Under: Current awareness • E-mail links from many journals at the article level

  38. Other Tools • Next Wave • EndNote • Bibliographic management database

  39. EndNote • Import citations from databases • Convert citations to style needed for publication

  40. Remote Access • Internet Toolkit (Shiffman Circulation Desk or Undergraduate Library) • Access ID (aa1234) • Dial-in/proxy authentication • Instructions on Shiffman web page

  41. Other “ID” • One Card is library card (# on bar code) • Check-out/renew books • Enter library • Computer lab authentication • School of Medicine only • http://accounts.med.wayne.edu
