Anybody find a license for their online catalogue? Searching for license found one "resultaten" that was a link that 404's, and no hits for "licentie."

Along those lines, though, this: https://www.veradekok.nl/en/2015/08/introducing-the-dememori...

will let you download full page images. and I think this: https://github.com/lovasoa/dezoomify/issues/209

Should work, also. I don't know Dutch law, but I would think books this old would have to be public domain.

Yes, the dezoomify extension will get you individual pages, quite neat seeing the image getting put together client-side in a canvas.. shame it's even necessary though.
