Elsevier, a publisher of scientific, technical, and medical (STM) information, has announced that more than 900 research libraries and corporations from all over the world are participating in the trial of eBooks on ScienceDirect. The trial will provide participating institutes with preliminary access to 500 of the 4,000 scientific and technical books that will be launched on ScienceDirect in the third quarter of 2007. At launch, the program will comprise selected titles published from 1995 to the present day. The books will cover scientific disciplines, including those published under the Pergamon and Academic Press imprints. Following the launch, approximately 50 newly published titles will be added to the eBooks list on ScienceDirect each month, offering researchers integration and linking between the latest online book and journal information. The ScienceDirect eBooks program will render these and other authoritative titles fully searchable and linked not only with referenced book series, handbooks, and reference works but also a repository of full-text journal content.
