- Abstract
- Many retrievalexperiments are intended to discover ways of improving performance, taking the results obtained with some particular technique as a baseline. The fact that substantial alterations to a system often have little or no effect on particular collections is puzzling. This may be due to the initially poor seperation of relevant and non-relevant documents. The paper presents a procedure for characterizing this seperation for a collection, which can be used to show whether proposed modifications of the base system are likely to be useful.

- Abstract
- A method is outlined which would permit a large number of libraries of all types to use centralised cataloguing facilities without the need for their own automatic data processing equipment and outlay. The method is seen as an alternative to the OCLC on-line data bank, and permits the ordering of printed catalogue cards by machine-readable but hand-prepared data cards, such as the loan cards which readers at the Münster library are at present required to complete. The proposed sequence of ordering is set out in 11 stages
