In an exciting development for the open access and repository movement, Thomson Scientific has announced that it is teaming with NEC and several other agencies to create a Web Citation Index, which will become part of the Web of Knowledege platform.
The Web Citation index will do for open access documents, including pre-prints and items in institutional repositories, what Thomson's other citation indexes currently do for peer-reviewed journal literature. Researchers will be able to follow citations to open-access documents backwards and forwards, and citation frequency and trends will be recorded.
