Abstract
Thomson ISI has announced the Century of Science initiative. Currently, Web of Science coverage extends to 1945. The Century of Science initiative will expand the Web of Science to include bibliographic data from the highest impact scientific literature published between 1944 and 1900, adding nearly 850,000 articles from approximately 200 journals. The jour-nals have been carefully selected by the Thomson ISI editorial team, based an such criteria as citation patterns, geographic origin, and meaningful balance across scientific disciplines. The Century of Science initiative will extend through 2004, with the new material available to customers in 2005. Using the historical data that will be available, researchers will be able to track published research concepts retrospectively back to the beginning of the 20th century and consequently develop a greater understanding of prior developments. Currently, Web of Science indexes approximately 8,500 scholarly journals, providing users with complete bibliographic data, searchable author abstracts, and cited references. Web of Science is a key component of ISI Web of Knowledge, the single Web environment from which researchers can access, analyze, and manage information. Thomson ISI (http: //www.thomsonisi.com) is a business of Thomson Scientific, part of The Thomson Corp. [Die Kosten für den Kauf der ISI Backfiles würden sich für ein österreichisches Konsortium auf USD 800.000,-, zahlbar in drei Jahresraten, belaufen. Anm. d. Red.]
