Beautiful. What a wonderful way to navigate a periodical. Any chance you could open source this implementation? There are plenty of magazines that I'd love to search in this format (eg Sound on Sound).
I found an article[1] in the archives of BYTE magazine[2] - and was captivated immediately by the tech adverts of bygone eras.
This led to a long side project to be able to see all 100k pages of BYTE in a single searchable place.
