Exploration of the deterioration of theses at two New Zealand universities libraries

Abstract

A survey of theses was undertaken at two New Zealand universities to assess the current state of deterioration of the materials used in producing (making, or constructing) theses. 223 theses were examined at the University of Auckland and 184 at the University of Waikato. Theses were assessed for discolouration of paper, stability of ink, legibility, discoloration of photographs, and methods of adhesion. Despite concerns regarding the legibility and integrity of materials used in construction of theses expressed overseas it was found that no individual thesis had suffered irretrievable loss of legibility and only one of those sampled was of cause for concern. It was notable that this was not one of the older of theses. In general the oldest theses were in good condition though the paper used had usually discoloured. Of greatest concern were problems caused by the breakdown of adhesive tapes, which resulted in loose illustrations, and discolouration of many photographs and adjacent pages. Modern technology for producing theses may have reduced this particular problem. Electronic deposition of theses is already in place in a few institutions overseas and if it is achieved here will solve storage problems and improve access to theses which are born digital. There will however still be the problem of the currently stored theses and their preservation. This is not an urgent issue, as the currently stored theses appear to be maintaining reasonable condition. It is recommended that programmes to inspect a selection
