  1. Searching and Organizing the Literature Dolores Zegar Judkins, MLS Head, Instruction, Research & Outreach OHSU Library judkinsd@ohsu.edu

  2. Ways to get help: Ask a librarian Chat Email Phone

  3. Barcode • You need one • Where you can get one • Library circulation desk • Online at www.ohsu.edu/xd/education/library/services/forms/barcode.cfm

  4. Where to find your information • Library resources • Online catalog • Databases / journal articles • E-book collections • E-Reference • Ask a librarian

  5. The Library Home Pagewww.ohsu.edu/xd/education/library/ This is where you get to all the resources the library has to offer Research Assistance Get access from off-campus Online Catalog Get help List of databases

  6. School of Nursing Resourceswww.ohsu.edu/xd/education/library/services/library-resources-for-son.cfm

  7. Online Catalogcatalogs.ohsu.edu/ • The catalog lists books and journals that the library owns • Lets you know if the library owns a journal and what years the library has of that journal and if it is in paper and/or electronic format • If the journal is available electronically, there is a link to the electronic version • You cannot search for journal articles in the catalog – use one of the databases

  8. Online CatalogFor resources at OHSU

  9. And, if the OHSU Library doesn’t have the book, try the Summit button OHSU Library does not have Harry Potter. Search Summit to see if the book is available.

  10. Summit Catalog • Includes 36 college and university libraries in Oregon and Washington • You can request books, videos, CDs through Summit and they will be sent to the OHSU Library for you to pick up or will be sent directly to distance students • Generally it takes less than 72 hours to get the book • 95,000 titles at OHSU; 9.2 million titles in Summit • IT’S FREE • More information at www.ohsu.edu/library/orbiscascade.shtml

  11. You can go directly to the Summit Catalog, but it’s best to try the OHSU catalog first

  12. E-journalscatalogs.ohsu.edu/search~S5 • The Library has many electronic journals available, but you have to be aware that not every title includes all issues electronically • Most journals do not have electronic access prior to the mid-90s • Some journals are “embargoed”, which means that the most current issues are not available electronically.

  13. If you know which journal an article is in, you can go directly to the e-journals page to see if we have the journal, and if we do, you can then get the article online from the link in the journal record Type in a title or keyword, or find journals through a subject listing

  14. Make sure you look at the information about the journal to see what years are available. Info on years available electronically Link to full text Info on years available in print

  15. Single Citation Finders There are ways to find a single citation in PubMed, Ovid, and CINAHL. Instructions on how to find single citations are at: http://www.ohsu.edu/xd/education/library/databases/citation-finder.cfm

  16. Finding a single citation in Ovid

  17. Finding a single citation in PubMed Single Citation Matcher

  18. You don’t have to fill out all the fields, just put in enough information to get the citation

  19. Finding a single citation in CINAHL

  20. E-Bookswww.ohsu.edu/xd/education/library/books-journals/ohsu/e-books.cfmE-Bookswww.ohsu.edu/xd/education/library/books-journals/ohsu/e-books.cfm The OHSU Library has access to many books online. You can search entire collections, or you can search the catalog for a particular title. The webpage includesinformation on how to find electronic books in the catalog, as well as a list of the collections the library has.

  21. Stat!Ref A number of basic medical texts Rittenhouse Books on medicine and nursing AccessMedicine Basic medical texts Stat!Ref A number of books on health related topics http://www.ohsu.edu/xd/education/library/ books-journals/ohsu/e-books.cfm

  22. Search the catalog for e-books

  23. Databases / Journal articleswww.ohsu.edu/library/databases/ • Databases include indexed articles from thousands of journals • Some databases just have the citation and abstract of the article, some include the full text • Many databases allow you to link out to the full text of articles • The OHSU Library has over 100 databases listed on its database page

  24. Access to Databases Easiest way to get To the databases

  25. Top Databases • Some of the most relevant databases for nursing students are • MEDLINE • CINAHL • Scopus • Nursing Reference Center • Nursing and Allied Health Source • Includes Joanna Briggs Institute

  26. Searching tips • Combining terms (and, or, not) • Database specific vocabulary vs. free text • Explosions • Truncation • Synonyms, variant spellings

  27. MEDLINE • For most health topics, the top database to use is MEDLINE • MEDLINE is produced by the National Library of Medicine • MEDLINE contains more than 19 million citations from over 4,800 journals • Contains information on all the health sciences fields as well as the basic sciences • There are two main ways to get to MEDLINE • Using the Ovid interface - Ovid MEDLINE • Using EntrezPubMed - PubMed

  28. MEDLINE (Ovid)www.ohsu.edu/library/ovid/ This is where you get into the Ovid databases. You will then select the database you want to search.

  29. Ovid databases

  30. Tips for a Better Ovid search • Ovid has some unique ways of searching, so it’s best to look at a guide if you want the most effective search • It is best to search one database at a time, rather than multiple databases • The new interface has a Basic Search tab that has some serious problems, so librarians at OHSU suggest you stay away from it

  31. Ovid: using subject headings Let the database look for the indexing terms.

  32. Mapping to subject headings

  33. Ovid: selecting your subject heading A number of subject heading suggestions for the word “informatics”. Click on the word to see the “Tree Structure”.

  34. Ovid: Scope notes Using the Scope note gives you valuable information about the subject heading you are using. Year of entry is especially important.

  35. Ovid: the Tree Structure Broader subject The subject More specific subjects

  36. Ovid: Explosions Clicking on the “Explode” box will get you not only the articles that have “Communication” as a subject, but also, all the subjects that are more specific. There are 20,368 articles with the subject “Communication”; if you explode, you get 117,210 articles.

  37. Ovid: Combining concepts Combine terms to narrow down your retrieval.

  38. PubMed • Contains MEDLINE and links to a number of other databases • Make sure you use the OHSU PubMed link. This version links to the e-journals that OHSU subscribes to • PubMed has a great guide available for effective searching • nnlm.gov/nnlm/online/pubmed/pmtri.pdf

  39. PubMed at OHSU Use the OHSU PubMed link to get access to OHSU e-journals

  40. PubMed Learn to use PubMed

  41. CINAHL (EBSCOhost) • A nursing and allied health database • Some duplication between MEDLINE and CINAHL • Much smaller database than MEDLINE

  42. CINAHL CINAHL is searched somewhat differently than Ovid or PubMed

  43. Scopus • Covers life sciences, health sciences, physical sciences, and social sciences • Indexing of nearly 18,000 journals • Half of the records go back to 1996 and include citation data; some records go as far back as 1823 • Includes all of Medline and most of Embase • Includes citing information

  44. Citing information

  45. Google Scholar: Searchscholar.google.com If you’re going to use Google, try Google Scholar. It has information that may not be available in other databases that are available to you.

  46. Google Scholar: Results Includes books, articles, Web pages. Has “cited by” Information. But look at the number of hits!

  47. Google Warning No matter what the subject is, you will almost always get thousands more citations in Google or Google Scholar than you will in a database that uses a controlled vocabulary, such as Medline or CINAHL.

  48. Electronic articles and journals are linked from within databases. Databases may include their own links to full text, as well as the “Find It@OHSU Library” link. 3 different ways to get to the article
