I got a kindle Scribe which can load PDF, HTML and text files via iPhone Kindle App and read offline.

Since most pre-1925 books are out of copyright and free on https://gutenberg.org, ACM is open access (https://dl.acm.org/) and we have open https://arxiv.org/, it is the golden age for readers seeking original content.

We don’t need bots to read for us. We can live in the mind of human writers.

Are technical/scientific books from pre-1925 particularly useful for self-learning today? I'd imagine for most disciplines, the knowledge has progressed and possibly changed course since then and it may be more outdated than not.

		It might depend on the topic. Classical mechanics? I'm not sure that there is any fundamentally new knowledge since 1925 in that field. What's different is that people have 100 more years of figuring out how to explain it well.
