AISR staff have been busy this summer, improving JEFFLINE's Ovid interface and adding new databases and electronic books. The new Ovid interface offers new features and more timely information. When connecting to Ovid Online, you now connect directly to the Ovid company's servers, where information is updated "hot off the press." Ovid Online also provides additional databases: PreMEDLINE, and the Evidence-Based Medicine Reviews databases - the Cochrane Database of Systematic Reviews, Best Evidence and the Database of Abstracts of Effectiveness (DARE). Two new electronic books through Books@Ovid and Harrison's Online were also added to the JEFFLINE's growing collection of e-books. The first change you'll notice in Ovid Online is the ability to search multiple databases at once.

Choose the databases you want to search, then enter your search terms. Because different databases use different vocabularies, your terms will be searched in the default fields for each database.	(click image to enlarge)
Then use the Remove Duplicates feature to eliminate duplicate citations from the different databases.	(click image to enlarge)

Obtaining print copies of articles has also been simplified:

• Local holdings messages identify which journals you'll find at Scott Library.
  

• The Order feature allows you to order copies of articles through JEFFDocs document delivery or Interlibrary Loan fees may apply.
  

Ovid Online offers four new databases: PreMEDLINE, and three Evidence-Based Medicine databases: the Cochrane Database of Systematic Reviews, Best Evidence and the Database of Reviews of Effectiveness (DARE).

Evidence-Based Medicine Reviews
These three databases provide structured reviews of the medical literature, to help clinicians identify methodologically sound and clinically relevant research. A new limit can restrict Medline search results to articles appearing in the Evidence Based Medicine databases. (For an informative overview on using these databases, see Hunt DL, et al.: Users' guides to the medical literature: XXI. Using electronic health information resources in evidence-based practice. JAMA. 283(14):1875-9, 2000; available through Journals@Ovid.)

Cochrane Database of Systematic Reviews

The Cochrane Database, from the international Cochrane Collaboration, systematically reviews controlled trials of therapeutic interventions, with findings presented as ongoing protocols or completed reviews.

An electronic version of the ACP Journal Club (incorporating the journal Evidence-Based Medicine since January 2000), Best Evidence provides structured abstracts reviewing significant articles from 150 medical journals.

DARE, produced by a branch of the British National Health Service, also provides structured reviews of clinically significant articles.

PreMEDLINE
PreMEDLINE, our other new database, provides an additional tool for current awareness. Indexing articles with subject headings and tags can delay an article's inclusion in MEDLINE by several months. PreMEDLINE contains citations to newly published articles as they are being indexed, providing currency with keyword searchability.

New Electronic Books
Books@Ovid
Books@Ovid provides the fully searchable text of two textbooks: the Lippincott's Nursing Drug Guide and Fischbach's A Manual of Laboratory and Diagnostic Tests.

Harrison's Online
Harrison's Online is a fully searchable online version of the classic internal medicine textbook. Harrison's Online also includes clinical trials related to internal medicine, pretests for review of topics, and selected Internet links for additional reference. The contents are continuously updated.
