I guess one danger is that they only serve the page that contains your link to the webmention-validating request. That way they get a backlink but don't have to keep a public outgoing link. They'd have to know that a given request is that validation though, and I'm not sure that'd be very easy.

I know some people use S3 services for hosting images, but then you have to worry about generating your own thumbnails etc. and it's trickier.

I think it's mainly PVC that's to be avoided for archiving, and office supply shops are full of the stuff (document sleeves, etc.).

An archivist once told me that if you burn a bit of plastic and it doesn't give off any smoke then it's likely polypropylene or similar, and so good to use. That's never felt like a particularly robust test though (but I'm not a chemist).

One thing that wasn't covered, that sometimes matters for non-institutional collections, is that cardboard is thicker than plastic, and can add quite a lot to the number of boxes required for a given collection. Polyester or polypropylene sleeves (open at the top, and stored vertically, i.e. to allow gas exchange) can be as cheap and sometimes are a better option, at ~0.08 mm vs ~0.5 mm.

If the documents you have are able to be made public, you could upload them to Wikimedia Commons and use https://ocr.wmcloud.org/ — you can use Transkribus via that. (Disclosure: I'm an engineer working on the Wikimedia OCR project.)

I recently added support for it to my blog (which uses twyne.rtfd.io) so I could more easily geolocate photos (from my non-GPS camera), and it was pretty easy to integrate. I tried GPSLogger too, but found that battery life was much better with Overland, and it also has a better system of queuing points when offline (with GPSLogger I found that it lost data at times such as when there was an internet connection but the server wasn't responding).

Anyway, here's an archived version: https://web.archive.org/web/20211102003457/https://www.nbcne...

I think it might be the other way around: pigment-based inks are opaque particles bonded to the paper, and so even if their colour changes/fades they're likely to still be legible. Whereas dye-based inks, when they fade, can completely disappear. (One advantage of dye-based inks is that they have a larger gamut.)

I wonder what the "100 year plan" will be. Flickr does seem like one of the few places that could conceivably store copyright photos for as long as it takes for them to become public domain (i.e. it's worth it, because they keep the full-res originals and lots of metadata).

Of course, the vast majority of photos on Flickr could probably be made CC-BY-SA now by their owners (i.e. everyone who's not making money out of their photography). I think more should be done to encourage people to do that.
