Abstract
The Central Library and Documentation branch of the ILO conducted a survey of users' needs to enable it to adapt its catalogue system to deal with the problems of scattered offices and a wide range of subject‐interests. A cross‐section of the CLD's users was interviewed, and filled out questionnaires which dealt with documentation needs in general, but focused in particular on the use made of the existing catalogues and what users ideally required. Results confirmed that the existing catalogue was too inaccessible, and indicated the type of indexes which, used in a system of co‐ordinate indexing, could make documents more easily known and available.
