Conservation Housing: Medieval manuscripts

I am in the finishing-up stages of a very enjoyable project to rehouse a group of medieval manuscripts in the Special Collections. The Abbey Dore collection (currently cataloged as MS 191, but soon to be located at MS Q80) includes fifteen parchment manuscripts from the 13th century. Some of the documents have pendant seals attached, and all were housed in a slim manuscript case in folders fitted with polyester film supports inside.

While this system allowed the manuscripts to be stored upright in folders, which is certainly convenient, it is not the ideal situation for such documents. The polyester film has sharp edges that could potentially cause damage to the seals or documents, and some of the seals are heavy or broken and in need of better support. In discussions with curators and the manuscripts processing coordinator, we decided to rehouse the manuscripts in flat enclosures. The collection will now reside in three flat archival boxes, a challenge for the stacks manager who had to find the space to put them, but all agreed that flat storage would be best for these materials.

Because these documents have information on both recto and verso, the curators desired that researchers could view both sides with minimal handling of the fragile items. I made a mock-up enclosure that we looked at together, and after some troubleshooting we devised an enclosure with two mirror-image, soft Tyvek-lined cavities. This enclosure can be gently flipped over and opened from either side to view both sides of the document. Plastazote foam bumpers protect the seals from shifting, and each enclosure will be labeled with instructions for use.
