Online access to journal abstracts and articles.

Advances in information technology now offer several options for child and adolescent psychopharmacologists to navigate the increasingly complex terrain of scientific literature and keep abreast of the rapidly changing advances in our field. MEDLINE, the world's largest database of medical literature, can be accessed and searched by a variety of free or fee-based services. In addition to efficient retrieval of citations and abstracts based on subject, author, or title, many of these services now provide, for a fee, the entire text and graphics of articles (displayed on computer screen, faxed, or mailed). There are also current awareness services to alert the user when new requested literature become available as well as services to send via e-mail the tables of contents of requested journals (sometimes prior to paper publication). For online citation and abstract retrieval, we found that free services, such as PubMed, performed as good or better than fee-based services. Physicians' Online, sponsored by the pharmaceutical industry, offered the lowest price for full-text manuscript delivery. In this article, we review literature search, delivery, and update services and offer some tips on how to most effectively use these resources.
