Electronic publishing in radiology: beginnings, current status, and expanding horizons.

Electronic publishing in radiology began in the 1980s and gathered momentum as use of the personal computer and subsequently the World Wide Web became commonplace. The ease of access and wide distribution that the Internet affords have presented both experts and lay users with the challenge of distinguishing reliable from unreliable material. In the field of radiology, peer-reviewed journals, the sine qua non of reliability in the scientific realm, began to appear in online versions in 1988, and now, nearly all such journals currently have online versions. Electronic versions of textbooks and textbook-like material have become more common, although the vast majority of publishers' catalogs are traditional print books. Electronic material is more common in the fields of internal, emergency, and family medicine than in the field of diagnostic radiology. The latest publishing medium is the personal digital assistant. Challenges that face electronic publishing include the issues of permanent archiving, citation, and indexing. Peer review seems to be the best method for distinguishing reliable from unreliable information. The use of Web technology has improved the logistics of peer review, and some journals have begun posting peer reviews themselves on the Web alongside peer-reviewed articles. Electronic publishing has changed the manner in which radiologists obtain information, providing wider, more immediate access.
