You can find The Art of Electronics on the internet... And you can put it on an old tablet with dozens of other reference books.
Furthermore, plenty of stores sell you files to consume however you want.
Oh and e-ink works fine in sunlight and lasts weeks without charging. And FYI, there's plenty of notetaking systems.
My partner and I have been using these e-ink devices for almost five years. Works fine. No replacement required thus far. It is a specialized version of Android.
The World Book entry on enormous subjects of great importance was still maybe a few pages long. Today, a fair amount of primary source material in archives on different freaking continents is available online.
Printed documentation for hardware and software was frequently not exhaustive and there was no way of asking for help quickly. Maybe you had a help line. Maybe you knew hobbyists in a local meetup group. But that old DOS manual wasn't anywhere near as useful as what is available today.
For example, when I tried picking up electronics as a curious high-schooler, I managed to pick up a clearance sale copy of The Art of Electronics - it had all the information I could possibly look for (and I'm pretty sure once could make a career in Electrical Engineering using nothing but that book as a source even today). I'm pretty sure I'd be hard-pressed to find such an accurate and comprehensive reference on that topic anywhere on the internet.
