13.2 E-Journals

E-journals form a large part of the collection of a library for providing web based services. Today
many journals are available electronically - some are full text and some contain only bibliographic
information with abstract. Major advantage of electronic journals is that they are constantly updated
and easy to access but disadvantage is that breaching of copyright law is very easy. They are available
as bitmaps, PostScript, PDF, ASCII, SGML and HTML. Library services may be delivering to users on
CDRom, through email or through web. Some international societies and associations have developed
their own digital libraries through which users can get access to all their publications. Services are
available to the members of society or associations through subscription.
The following are the key e-journals:
1. ACM Digital Library (http://portal.acm.org/portal.cfm)
2. EBSCO databases (http://search.epnet.com/)
3. Elesvier’s Science Direct (http://www.sciencedirect.com/)
4. Emerald full text (http://iris.emeraldinsight.com/)
