boon to scientific publication. It lets researchers disseminate their reports faster and at lower cost than ever before, greatly increasing the number and diversity of easily available publications. At the same time, however, the acceleration of publication has increased the perceived information overload for researchers attempting to keep abreast of relevant research in rapidly advancing fields. Scientific literature on the Web makes up a massive, noisy, disorganized database. Unlike large, single-source databases such as a corporate customer database, the Web database draws from many sources, each with its own organization.
