At the beginning of this year (see Science, 1 January 1999, p. 32), we briefed our readers on the features of our online products, all readily accessible from our main Science Online home page at Even in the short interval since then, our online technology partners at HighWire Press have worked with our editors to bring you further enhancements. Perhaps our boldest new adventure—into the world of online knowledge environments—is accessible now. At the risk of excessive chest beating, permit us to offer a brief summary of these newest tools.

Our most ambitious feature is an innovative guide for readers through the ever- enlarging morass of new findings. Now online is an exclusively electronic publication called Science's Signal Transduction Knowledge Environment (STKE). Science's STKE takes advantage of new information technologies to deliver to scholars essential information and to enhance their ability to integrate that information into useful knowledge and testable theory. What exactly is STKE? On one level, it is an electronic journal, updated weekly, with original Perspectives and Reviews on topics of broad interest from leading experts in the field of signal transduction. The STKE Reviews will be updated regularly by the authors with new information and thus will remain not only authoritative but always up-to-date. STKE is also a powerful electronic library. As noted by Bryan Ray, Science Senior Editor and now editor of STKE (see Science 30 April 1999, p. 755), readers can gain orientation within the often mind-boggling array of acronyms that describe complex signaling pathways and see their favorite transductive element's location within a map of signaling pathways. Within STKE is the Connections Map, an interface to an extensive database of information on components of signaling pathways and their relations, supplied by leading authorities in the field. Full text of the literature from 30 cooperating top journals will be accessible through the map or through our “Virtual Journal of Signal Transduction.” All this and more, plus weekly highlights to keep you aware of what's hot in the signaling literature, is available from your computer desktop. Initial response to the site has been terrific, and we are pleased to invite all of you to explore the newly launched site at

Science has long recognized the value of electronic links between the references cited by our authors and the abstracts and text of these previously published papers. Since 1996, we have provided such online linkages to articles in the journals archived by the National Library of Medicine (NLM). Now, papers published in Science since July 1997 will also carry links to abstracts on the Institute for Scientific Information's (ISI's) Web of Science citation indices. This vast compendium includes journals from a wide variety of fields, including the physical sciences, and identifies related papers and ranks them according to the number of references shared with the Science paper (the more shared references, the more related the papers). As new issues appear, ISI links are added within 24 hours. We hope that all of our subscribers will take advantage of this new feature.

We've also enhanced our links to NLM's PubMed with the addition of CiteTrack alerts. CiteTrack alerts readers when new material is added to PubMed or to one of the journals electronically published by HighWire that matches the reader's preselected search criteria for authors, keywords, or citations. Moreover, we've continued to add to the online Enhanced Perspectives, which form the hub of a hypertext-linked online web of information relevant to the topic of the original Perspective. Now organized into 43 topic headings, the Enhanced Perspectives extend back to February 1996 and will soon be joined online by a weekly list of books received at Science, also accessible by topic through our subject collections.

Praiseworthy as we think the current set of electronic tools may be, their purpose is to help the reader stay afloat on the seas of data. We await your requests for tools we've not yet imagined.
