They are becoming more popular for accessing, retrieval and offering services electronically, replacing gradually their print counterparts. During the last three decades, the information formats and delivery systems have changed considerably. Timely delivery of extremely current information has always been a crucial factor in special libraries. Moreover such libraries have always dealt with a diverse range of non-book information and material, most of which is inherently suited to electronic format.

The need to reduce the time required in conventional publishing and the realization of the potential and unique feature of electronic media are some of the reason which have resulted in the shift of emphasis from conventional publishing to electronic publishing. There are four main reasons for the development of e publishing
Rapid development and wide use of computer technology.
Tremendous growth of computer networks.
