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.

Though it is a pleasure to write a short foreword to this collection of excellent scientific papers covering a range of biological topics, the rather depressing feature is the small number of papers. All-electronic publishing is developing and your Editors do have great faith in it. One problem for potential authors has been the reluctance of the abstracting journals to pay any attention to electronic journals - perhaps Springer should make a rapid move in this area and start the first all-electronic journal abstracting this type of literature. However, even the paper citation journals are starting to pay attention to the medium. The particular advantages of all-electronic publishing are beginning to emerge more clearly and it is clear that publishing video material is a unique advantage of our format. Several papers took advantage of this - for example those by Riehle and others on cell behaviour in tunnels, by Bereiter-Hahn and Voss on zonation in the plasmalemma and by Pavlikova, Zicha, Chaloupkova and Vesely on cell motility of tumour cells. These papers made essential and extensive use of video material, publishing some material of great originality. The work on cell pola rity and calcium ions in Fucus embryos by Brownlee, Manison and Anning used animation to present their results in an especially clear way. The facility of use of animation is another special advantage of our type of publication that should be more widely used."
