I am rather excited to learn that Leiden university library apparently allows readers to photograph manuscripts themselves! Details here:
They don’t allow flash (understandably) or tripods (less so). But this is great news!
If anyone would like to try this out and see how it works, I think we would all be interested.
The reproductions department doesn’t seem to have heard of supplying microfilms in PDF form, tho. I’m querying that with them.
