The Archive is a complementary part of the Collection. It has been established from the documents, papers, photographs and plans retained by the late Bess Jamieson among others. In addition, it includes a record of the exhibitions held annually over a thirty five year period. To accompany the exhibitions background material is kept in a set of Research Files which is included in the Archive.

A recent generous donation from Louise Irvine is currently being added to the Archive. It charts her knitwear business through the 1980s into 2000 providing an interesting record of Shetland knitwear during that period.
