commentThe publishers are pleased to announce that, from this issue, Information Tech­
nology will be published in a new expanded format. This change reflects our intention
to provide the most complete source of information available to those working in
information technology.
Since its launch, Information Technology has become firmly established as a lead­ing journal in the field of information storage and retrieval. It is now taking on new
responsibilities. While the journal will continue to provide the highest quality
research papers, of the same standard that our readers have always expected andreceived, it will now offer an even more comprehensive information package, taking
in the ‘sharp end’ of information technology at the application level.
Another new service will be the provision of updates on the activities of relevantorganizations and special-interest groups. The journal will also carry detailed con­ference reports and a full events calendar, covering conferences, courses andexhibitions.
These changes bring Information Technology to the forefront of the revolution ininformatics. The journal will, together with its sister publication Information Age,
which covers information management, policy and social issues, provide access tothe thoughts and theories of the leading professionals in the world of informationtechnology, from researchers to policy makers.
