Yes it's a fair amount of data:

pdfs/ 12.5 GiB

pages/ 91.96 GiB (Each page as a .png)

text/ 365.03 MiB (Each page as text)

byte_files/ 55.98 GiB (The 1024x1024 tiles as .jpeg)

I had not heard of https://github.com/lovasoa/dezoomify-rs before, that's really cool!

Oh interesting, thank you! I live in Cambridge an often walk past the Sinclair building but I had not heard of Lynx or Ace which are also based in familiar places! https://byte.tsundoku.io/#198301-050
