I ahve a collection of old whiskey advertisements that was given to me by a friend who decided to narrow his focus from bourbon in general to Lexington distillers. I also have some other paper materials such as a prohibition perscription, some labels and a warehouse receipt. Being an archivist by trade I keep these materials in acid free folder and stored flat in a room that is cool and humidity controled. I thought that I might share some advise on caring for paper artifacts that might be part of your whiskey collection.
1) You must understand that paper has natural acids that will cause the paper to yellow and turn brittle. You can spend money and send this paper to a conservator who will treat it to neutralize the acid but that is expensive. Archives only do that for the most valuable of documents. They can be kept in mylar sleaves that will allow viewing but prevent damage from casual handling.
2) Sunlight speeds the damage from acid in the paper. If you frame an item, make sure it is mounted on acid free board and has uv preventive glass. Also do not hang it in direct sunlight. The best thing to do is to make a color scan of the object and frame the scanned image and store the original away.
3) Paper should be stored in acid free folders and stored flat in a humidity and temperature controled environment. A file cabinet can be used as storage if the folders are kept tight in an upright position, but gravity can cause curling or even cracks in the paper if the folder is not tightly held upright. Paper should be unfolded as much as possible before storing.
4) Binders with plastic sleeves are a cheap way to store collection but make sure the sleeves are a good quality material and if they start to yellow or get brittle, replace them.
There are some things that should be avoided at all cost.
1) "Magnetic Photo Albums" are to be avoided. These are the ones with the stick paper that holds the clear plastic down. The glue migrates into the paper and will destroy the item within a decade. It is also hard to remove the item from the album after a few years, often leading to damage from tears.
2) Scotch tape: The glue migrates to the paper and the tape yellows and disfigures as well. There are archival tapes made for those items that really need the repairs, but that should only be as a last resort.
3) Do Not Lamenate!!!! This process will eventually destroy the item as the glues in the lamenation migrate to the paper and the item con not be removed once lamenated without destroying the paper.
4) Do not expose paper to direct sunlight. Sunlight will destroy paper and fade ink. If the sun shines directly on a framed item then move it somewhere else.
I hope you find these tip helpful.
