Do your library users search PubMed from the National Library of Medicine? Would it be useful to inform your users on a PubMed citation whether your library has electronic access to the full-text? You can do so by participating in LinkOut.
LinkOut is a feature of Entrez, an information system developed by the National Center for Biotechnology Information at the National Library of Medicine. LinkOut provides an integrated information space, which allows users to move seamlessly between PubMed and other Entrez databases to a variety of relevant, web-accessible online resources provided by third parties.
LinkOut in PubMed allows a library to choose which full-text providers to link to. This includes publishers of electronic journals and all full-text providers that participate in LinkOut. In addition, a library can supply links to locally-loaded journal collections or any e-journal collection for which the library can provide reliable URLs. Consequently, a library can easily setup an environment for its users that features seamless and appropriate links to its electronic collection.
The majority of links in PubMed point to online journals, but the scope of LinkOut exceeds that. LinkOut includes information that is specific to the subject area of PubMed citations and relevant to users' research and study. Currently, users can find links to consumer health information, commentaries on articles, authors' background and research interests, datasets of articles, practice guidelines, and more. In development is the ability to link to a library's print collection holdings. Through LinkOut, PubMed citations become an entry point to countless relevant resources on the web.
Libraries provide links to their e-journal collections via the Library LinkOut Files Submission Utility, where holdings are simply checked off. Use of the Utility is free to all libraries. For registration, please send a request to firstname.lastname@example.org and include the name of the library and a contact person, telephone number, and address.
