PROGRESS IN DOCUMENTATION

Abstract
In addition to providing a review of the literature recently published in the librarianship of non-book materials this survey aims to draw attention to the characteristics, problems and achievements particular to the documentation and handling of non-book materials (NBM) in many types of libraries. The materials are briefly described and considerations of selection, acquisition, organization, storage and in particular bibliographic control are dealt with in some detail. Other areas of concern to the librarian dealing with media resources, including the organization and training of staff, planning, equipment, exploitation and copyright, are also discussed. The past decade has seen the widespread introduction of NBM into libraries as additional or alternative sources of information. Librarians have been given an opportunity to rethink many basic principles and adapt existing practice to encompass the new materials. The survey reflects the achievements and some of the failures or problems remaining to be solved in this rapidly expanding area of library work.
