The administration of the LSUHSC Libraries is committed to providing electronic journals to our patrons without sacrificing the integrity of our print serials collection. Some publishers permit free online access with a print subscription, although many require additional payment. Among the titles available online are Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics; New England Journal of Medicine; Lancet; Laryngoscope; and Dental Clinics of North America, just to name a few.
Many journals have more than one access method, and restrictions on linking to full-text journals vary among publishers. The LSUHSC online catalog (Innopac) record for each title indicates what is available (full-text, abstracts only, or table of contents only) and how to access the journal. Most publishers require that access be limited to computers on the health sciences center network. In many cases you can retrieve an article at your desk, but for some titles, only a library staff member is authorized to access and print the full-text. For a number of titles, the full-text is available by searching in databases such as Ovid, MDConsult, Lexis-Nexis Academic Universe, or InfoTrac Web. Other journals, such as Acta Odontologica Scandinavica, Clinical Oral Investigations, and Calcified Tissue International, offer full-text online without any restrictions, provided you are on an LSUHSC computer.
Licensing agreements with some of the publishers limit access to one terminal in either the medical or dental library; others limit the number of simultaneous users having access to the text online. A message such as “Full-text access is available only through LSUHSC Library Staff. Request assistance at the Circulation or Reference desks” indicates that only library staff members are authorized to access the journal and print the article for you. While the online availability of journals changes constantly, the library continues to add online access to titles to which we subscribe. Feel free to contact the library with any questions you may have about online journals.
Grateful Med, one of the first systems available to health care professionals for searching MEDLINE, is the National Library of Medicine (NLM) search interface to its original mainframe databases. When PubMed was first developed as a free Web-based MEDLINE interface, NLM converted Grateful Med to Internet Grateful Med (IGM) so that it would also be free and Web-accessible. Because IGM remained on the old mainframe, NLM is now starting to phase it out and transfer its unique databases, such as OLDMEDLINE (1958-1965), AIDSDRUGS, and HISTLINE (History of Medicine), to other search systems.
MEDLINE is no longer searchable through IGM and NLM plans to complete the phase-out of other IGM databases by September 30, 2001. One option now available for searching NLM databases is the new NLM Gateway, which allows one entry point to all its different systems regardless of format or subject. The current Gateway searches MEDLINE/PubMed, OLDMEDLINE, LOCATORplus, AIDS Meetings, HSR Meetings, HSRProj, MEDLINEplus and DIRLINE. With Gateway, you can find journal articles, books, meeting abstracts, directory information, and full-text publications. For example, on the initial Gateway screen, if you enter “gunshot wounds” (enter phrases in quotes) in the box and click on “Search,” you will see the following screen indicating the number of hits in various categories
Click on “Display Results” for a list of brief citations in a category, which you can then expand to display the full citation. You can also search using the Boolean operators, AND, OR, NOT. To search for an author, you must enclose the last name and initials in quotation marks followed by [au] or [author].
The NLM Gateway provides a quick way to search various NLM retrieval systems, and is especially useful for searchers unfamiliar with specific databases. Direct access to PubMed, MEDLINEplus, and Locatorplus is still available. In fact, to run a focused MEDLINE search and to take advantage of its sophisticated features, search PubMed directly.
Once you identify the publications that you want, call the dental library. If neither this library nor the medical library owns the titles, we’ll order them for you via our Interlibrary Loan Service. For more information on the NLM Gateway, see the NLM Fact Sheet.top of page next page
