内容简介：
【简介】 The Yale University Science Libraries have implemented a Navigator system, designed by David Stern (Director of Science Libraries and Information Services), that helps users determine - and in many cases transparently link to - the most appropriate source for their information need(s) in the sciences.
This approach begins with the type of information desired ... a definition, short description, annual review, the latest information, etc ... and then moves on to subject and source determination. It assumes that users have no idea of the plethora of resources available upon entering an information maze. It attempts to identify the best and other relevant sources for a particular need.
