|Abstract: ||It was in 1953 that the train of events started which brought about my participation in the investigation which is the subject of this report.

an index designed for the retrieval of information in answer to very specific requests, and was far removed from the systems used in
conventional library indexing. In that the average time taken to index each document was 1.5 hours, it was comparatively expensive, although the cost was shared out on a subscription basis amongst a number of
Clearly, however, such an index could only be used
for a relatively limited range of documents that were of particular significance, and Thorne and I were prepared to accept the possibility
that in certain circumstances an organisation might be economically justified in maintaining two different types of indexes covering an
overlapping range of documents.
The Universal Decimal Classification
was widely used in England and, in spite of many criticisms, was on the whole meeting the requirements of its users for a general indexing
system. We were looking for another system which would fulfil the same function as the NLL scheme, but which might be less expensive
and therefore more attractive economically for a single organisation to operate.|
