This comparative survey of current practices in classification and cataloging of printed materials was concerned with six questions: (1) What procedures are involved in cataloging and classification? (2) Could some of this work be done by a centralized cataloging service? (3) Who is doing the work of cataloging now and what are his qualifications? (4) What proportion of library time and money is being spent on cataloging? (5) Is there any degree of uniformity in the cataloging practices of the various university libraries? (6) Are the resultant catalogs being used? The questionnaire used as a basis for the survey was distributed to sixty-nine British college and university libraries with a return rate of seventy-four percent. The information given relates to the situation as of the end of 1965 and for the purposes of the analysis the replies were categorized according to type and size of library. The major part of the document presents the analysis of each question in the questionnaire and also the relationships found among some of the questions. It was concluded that more study of classification schemes and the kinds of information desirable in a catalog entry is needed. The effective use of mechanized techniques in the future will demand more standardization of practices among librarians than exists at the present. (CM)
