In March 1996 the Society of Experimental Biology (UK) together with two other international scientific societies, the Australian and New Zealand Society for Comparative Physiology and Biochemistry and the Society for Integrative and Comparative Biology (formally the American Society for Zoology) joined forces with Springer-Verlag, Heidelberg to produce one of the first fully electronic online, peer-reviewed biological journals, Experimental Biology Online. The present product represents the fruits of this joint venture and encapsulates Volumes 1 and 2 of the journal. This will be an ongoing series such that an archival version of the journal will be available to all libraries as well as the on-line version. At the outset this was "new land" for all concerned but the launching of a journal which would cover experimental biology in terms of Animal, Cell and Plant topics was daunting but we all felt that the use of electronic media and the internet would be ideally suited to this purpose.
