This article addresses the collection management of electronic journals by libraries. The objective is to introduce the major issues and raise questions rather than provide comprehensive analysis or definitive answers. In fact, many of the important issues concerning electronic journal management may not have definitive answers at this time. A select, unannotated bibliography of English language items dealing with electronic journals, and emphasizing their management by libraries, is appended.There is no standard accepted definition of an electronic journal. The term covers a wide variety of diverse phenomena. For example, many different types of serials are now or will soon be available in electronic form, including: scholarly journals, popular magazines, newsletters, newspapers, and self-published zines. Electronic journals may be: electronic only; an electronic only version of a former print journal; or simultaneously electronic and print. The term electronic journal has been applied to journals that are available: by CD-ROM, such as ADONIS; online, as for example, through DIALOG; or networked, such as the Internet or Bitnet. Electronic journals can be: free; paid subscription; pay per use; or licensed for access rights. Some can only be subscribed to as part of a multi-journal package. Some electronic journals organize articles into issues, while others release articles separately. They can be stored on a local library or campus computer, or accessed from a remote site. Other phenomena that are not journals figure in the overall picture of electronic publishing, including publisher and journal home pages on the World Wide Web, academic conferences or discussion lists, and preprint servers on the World Wide Web.
