Advice on cataloging antique historic photos

Hey all!

(If this is the wrong place for this, please feel free to reassign)

During the winter months I can't get out to do much photography, but I love darkroom printing. Last winter I started buying antique photo negatives on ebay to have something to print.

It's been amazing! Many are from the 20's, 30's and 40's, with one set (of glass plates) having been manufactured pre-20th century!

I don't know how many I have, but it must be somewhere around 300-500 negatives. Currently they are stored in their original envelopes from the labs that developed them nearly 90 years ago, but that's not a good long term option. I love history, and I want to do this right, but I feel a bit overwhelmed with the volume.

Data I'd like to keep track of:

• The name of the person on the envelope the negative came from
• The date on the envelope
• The approximate date taken (if known)
• Ideally the specific envelope it came from

I'm going to try and store these in a binder of some sort, though that presents it's own challenges since it won't be possible to find sheets with sleeves that are the right size for the negatives. But that's a problem for me to solve haha. I've never had to index/catalog physical media before, so I'm pretty clueless on where to start.

More than anything it's really important to me to preserve this history in a safe way. For many of the people these pictures may be the only trace on earth that they ever existed, and I want to respect that.
