4.1 Content 

In addition to the non-patent literature mainly used for search purposes (see B‑IX, 3), the non-patent literature arranged for library-type access also includes literature which the search division can use as sources of information and for professional development and which covers not only general and background technical information but also new technical developments. The collection also includes reports, pamphlets, etc. Internet-based document delivery services of publishing companies are available to the search division members via an electronic virtual library (EVL).
