THE USE OF MICROFILM FOR COMPLETING SETS

There has been plenty of discussion of the technical problems of microfilming, and the potential importance of microfilms to the librarian is generally accepted, but little seems yet to have been written in this country on the practical problems facing the librarian who wishes to make extensive use of microfilms in building up his stock. Microfilm viewers are now to be found in many libraries, but on the whole, microfilms are used in British libraries mainly to satisfy occasional demands, and very few libraries in this country appear to be using microfilms systematically and extensively; an account of one such attempt may therefore be of interest.
