We are about to start processing our map collection Found In Collection and we use Past Perfect. It’s rather large with everything from ink on silk to canvas backed to paper, rolled mainly, some flat, everything. Includes rolled blueprints. Where do I go for conservation and preservation methods for these please? I read all the replies, numbers aren’t my problem, but want to make sure they are stored correctly. Too many to unroll, and we do have map cabinets. Not sure where to start?
