With the introduction of knowledge on standards for handling archives in the mid-1980s the Board established an Archives Advisory Committee to develop guidelines for the physical care and management of archival materials. Spear-headed by Val Billesberger, a volunteer, the committee forged ahead and established a separate administrative structure for the operation of the archives based upon internationally accepted archival principles and procedures.
Among the major projects undertaken by the Committee was the construction of a storage room in the Museum for archival holdings. Although the area would not provide adequate space to support the operations of the archives, it would establish for the first time, a central, secure place to house the unique irreplaceable archival holdings. Through a grant from the municipality, the assistance of local businesses and members of the Society, the room was built. On February 25th, 1989 Mayor Sophie Weremchuk cut the ribbon to officially open the Mission Community Archives marking its transition to a distinct branch of the Society. This occasion was highlighted by a generous financial contribution by the Mission Foundation to acquire proper equipment and supplies to furnish the archives.
In January of 1994, the Society received core funding from the District of Mission to hire the community's first paid Curator and Archivist. In April, Valerie Billesberger, a long time volunteer and graduate of the Masters of Archival Studies Program at UBC was hired as the part-time Archivist & Records Manager of the Mission Community Archives.
The dream first envisioned by the Society in 1983 became a reality less than a decade later. Construction on a custom-designed 3,000 square foot facility to house the Mission Community Archives was completed. The official opening on October 7th was attended by over 150 people including: John Bovey, Provincial Archivist and Carlene Whitney and Wendy Morris of Kamloops, the great grand-daughters of Anthony Talbut, Mission's first curator and archivist. The first of its kind in the entire Fraser Valley, the new state of the art facility established optimal space to preserve and make accessible the documentary heritage of the community.
