worldMEET: 会议信息数据库

TheScientificWorld is aimed at research scientists in the life and environmental sciences. It provides them with information services such as alerting, verification from several abstracting services and full text delivery to the desktop. In addition, it offers a digital publishing environment through a proprietary, multidisciplinary publication, TheScientificWorldJOURNAL. Through a relationship with Alchematrix, a wholly owned subsidiary of Fisher Scientific, it also enables scientists to purchase scientific equipment and supplies from TheScientificWorld's Web site.

The site's focus is on providing the end-user scientist with a comprehensive information service at the point of decision making. Pricing is flexible: customers can buy site licenses, open accounts for pay-per-view purchases or buy by credit card. The revenue earners are the company's proprietary publications, the document delivery service and revenues from the sale of equipment, supplies and biological resources. Some advertising and sponsorship revenues are anticipated. Alerting and verification are provided free at this time. WorldMEET, a database of forthcoming meetings and conferences, and NewsLAB, a customizable news service, are free.
