The aim of each volume of this series Guides to Information Sources is to reduce the time which needs to be spent on patient searching and to recommend the best starting point and sources most likely to yield the desired information.
The criteria for selection provide a way into a subject to those new to the field and assists in identifying major new or possibly unexplored sources to those who already have some acquaintance with it. The series attempts to achieve evaluation through a careful selection of sources and through the comments provided on those sources.

This completely revised edition takes account of the changing information scene e.g. in new chapters like Asia Systems, the big five countries in Africa and South America. This is an essential reference tool for academic librarians and information specialists as well as anyone needing to know where and how patent information can be found.
