Why only a subset of books? I'm guessing some relation to copyright or something similar?

It's a shame that the most common way to access digital books with libraries these days, is through a user-hostile DRM-infected system, held hostage by Adobe and publisher imposed limitations.

With that in mind I can only praise what Archive is doing, even if it's a subset being made available.
