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.

Recently, I've been thinking pretty hard about how to archive data. Optical media is out, due to my (possibly irrational?) fear of disc rot. HDDs just break with extended use, SSDs have been known to die with either overuse or just existing for an extended period of time. What's left?

I have heard of tape (of some kind) being used for backup in some bigger operations, but with my experieces with VHS, and to a lesser extent, cassettes, they seem to be very susceptible to mould.

Any suggestions?

IN A DUSTY ROOM in central Florida, countless millipedes, centipedes, and other creepy-crawlies sit in specimen jars, rotting. The invertebrates are part of the Florida State Collection of Arthropods in Gainesville, which totals more than 12 million insects and other arthropod specimens, and are used by expert curators to identify pest species that threaten Florida’s native and agricultural plants.

However, not all specimens at the facility are treated equally, according to two people who have seen the collection firsthand. They say non-insect samples, like shrimp and millipedes, that are stored in ethanol have been neglected to the point of being irreversibly damaged or lost completely.

When it comes to how the FSCA stacks up with other collections she’s worked in, Ann Dunn, a former curatorial assistant, is blunt: “This is the worst I’ve ever seen.”

Experts say the loss of such specimens — even uncharismatic ones such as centipedes — is a setback for science. Particularly invaluable are holotypes, which are the example specimens that determine the description for an entire species. In fact, the variety of holotypes a collection has is often more important than its size, since those specimens are actively used for research, said Ainsley Seago, an associate curator of invertebrate zoology at the Carnegie Museum of Natural History in Pittsburgh.

A paper published in March 2023 highlighted the importance of museum specimens more generally, for addressing urgent issues like climate change and wildlife conservation, with 73 of the world’s largest natural history museums estimating their total collections to exceed 1.1 billion specimens. “This global collection,” the authors write, “is the physical basis for our understanding of the natural world and our place in it.”
