7 Online Catalog –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 Catalog Online Catalog For 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

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

12 E-journals 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. Link to full text Info on years available electronically 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: brary/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


21 E-Books journals/ohsu/e-books.cfm 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 includes information on how to find electronic books in the catalog, as well as a list of the collections the library has.

22 books-journals/ohsu/e-books.cfm 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

23 Search the catalog for e-books

24 Databases / Journal articles Databases / Journal articles 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

25 Access to Databases Easiest way to get To the databases

26 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

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

28 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 MEDLINEOvid MEDLINE Using Entrez PubMed - PubMedPubMed

29 MEDLINE (Ovid) This is where you get into the Ovid databases. You will then select the database you want to search.

30 Ovid databases

31 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

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

33 Mapping to subject headings

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

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

36 Ovid: the Tree Structure Broader subject The subject More specific subjects

37 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.

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

39 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 –

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

41 PubMed Learn to use PubMed

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

43 CINAHL CINAHL is searched somewhat differently than Ovid or PubMed

44 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


46 Citing information

47 Google Scholar: Search 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.

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

49 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.

50 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

51 If we have the article Multiple ways of getting to this article.

52 If the library doesn’t have the journal, you can request the article here. If we don’t have electronic access, the “Find It@OHSU Library” icon will link you to into the catalog to see if we have only the print version of the journal, or if we have the journal at all. Check to see if the journal is available in print.

53 Interlibrary Loan

54 Tutorials The library has links to tutorials so that you can learn to use the databases well – assistance/ assistance/tutorials.cfm The library has classes on using our resources – -assistance/classes.cfm -assistance/classes.cfm

55 Reference Material The Library has collected links to a variety of websites that have valuable information You can browse the Reference Material page as you would a reference section in a library All resources are free to all


57 Managing Your Information Once you do a search of the literature, you can mange it by using a bibliographic management program With most programs you can download your citations directly into a database You are usually able to format papers using the software

58 EndNote / Reference Manager / ProCite Similar software produced by the same company Must load the software on your computer Can only be used on one computer Comparison of the 3 programs oducts/scholarly_research_analysis/authoring/endnote

59 RefWorks Is available free to all OHSU faculty, students and staff (subscription paid by OHSU Library) Is web-based, so no software is needed Comparison of RefWorks, Endnote, and Zotero (free software)

60 RefWorks You must sign up for an individual account before you can use RefWorks. If you have already signed up for an account, all you need to do is put in your Log-in name and password to get into your bibliographies.

61 The 15 minute rule If you’ve been searching for 15 minutes and haven’t found what you need, it’s time to ask a librarian.

62 Need help? We realize it can often get confusing. You can always ask for help in finding resources and information –Use the “Ask a Librarian” link on the library’s home page and send a message or use our chat serviceAsk a Librarian –Send a message to –Call 503-494-3462 and ask to speak to a reference librarian –Use the “Ask a Librarian” link within Ovid or CINAHL

63 Know when to quit How do you know you’ve covered all your bases? –Continued searching keeps bringing up the same articles –You’ve tried more than one resource –Some of your key articles are highly cited You’ll never find everything!

64 Final thought While using a database, when finished, look for a “log out” or “end session” tab. Many databases have a limited number of user sessions available, and forgetting to log out means the session will be held open for a period of time before someone else can get in.

65 Happy Searching Dolores Zegar Judkins, MLS Head, Instruction, Research & Outreach OHSU Library
