The 'UDC Pamphlet Collection' [Universal Dewey Decimal Classification]: In addition to the main Pamphlet Collection is the 'UDC Pamphlet Collection.' The UDC collection was the first pamphlet collection created by the Library and consists of approximately 10,000 pamphlets dating from mid nineteenth to mid twentieth centuries, covering all subjects. As the collection was gradually acquired during the Library's first 20 years of life, it was arranged by subject, using the Universal Decimal Classification system. The pamphlets were primarily deposited by organisations and individuals, although some purchases were made. There is a finding aid kept with the collection but the collection was never catalogued and therefore remained a hidden resource within the Library for more than 80 years. Unsurprisingly other libraries did not collect most of these pamphlets. In 2007 as part of a cataloguing funding bid preliminary sampling of the collection against Copac (the merged online catalogues of 24 university research libraries in the UK, plus the British Library and the National Library of Scotland) found that over 60% of the UDC pamphlets were not listed in these major research collections. This is a very significant level of unique printed material.Cataloguing of the UDC collection started in 2007 and as the pamphlets are catatogued, they are transferred to the main pamphlet collection described above. As at 2009 the collection was partially catalogued and The Library was seeking additional funds to complete the project.
