For about ten years I've had a nice little leather bound diary in my book collection. I bought it from an older woman who was cleaning out her home and found it in her attic. She wasn't even sure if it had belonged to her or was in the house when she moved in. The diary is dated 1799 and belonged to one Anne Pares. It apparently has her travels around Wales written in it (about a dozen or so pages).
I've stored the piece in a clear plastic bag (not airtight), away from sunlight and with my other books. I don't handle it much, but I wonder if there is anything else I should be doing to help keep this little fellow healthy. The writting inside is in black ink (which is turning a bit grayish brown in places). The pages are turning slightly yellow, but not that much. I guess if it survived in an attic for decades I can't do too much damage, right? Any thoughts?
