Scopus, an abstract and citation database of information and web sources, has announced a database which will provide customizable features to its customers. It enables users to search within selected repositories or subject specific digital archives within the Scopus interface. The new feature, Selected Sources, allows customers to choose from a list of institutional resources and subject collections indexed by Scirus, made individually searchable in separate tabs.
These Selected Sources can be selected and searched separately by universities, departments, and government agencies and corporations can enhance literature searching by providing access to non-published output such as theses, lecture notes, presentations, manuscripts, and prepress papers. It provides exposure of researches carried out at institutes that offer their repositories online. Librarians can choose from 19 institutional repositories indexed by Elsevier's Scirus including MIT OpenCourseWare, the University of Toronto's T-Space, the Caltech collection of open digital archives, and other literature sources such as NASA.
