National Library of Wales

In the 1930s, a major study was undertaken to determine the effects of different environmental conditions on over a hundred commercially- and experimentally-prepared leathers. Duplicate sets of books were bound with these. One set was shelved in the British Library, representative of conditions in a polluted urban atmosphere and the others in the National Library of Wales in Aberystwyth, a clean rural setting. The books were examined at regular intervals over a period of nearly 50 years for evidence of degradation.

New-combe, in a report of the Proceedings of the Sixteenth Coriference of the Association of Special Libraries and Information Bureaux, discusses the accessibility of British university thesis literature in 1939. En and, Wales, Ireland, and Scotland are covered. Newcombe lists British universities together with names of publications which list titles or give abstracts of university dissertations.
