It’s impossible to even get a sense of a textbook’s content from the so-called “previews” that you find on Amazon, Google Books, and the publisher’s’ websites.

It’s impossible to even get a sense of a textbook’s content from the so-called “previews” that you find on Amazon, Google Books, and the publisher’s’ websites. I prefer print, so I’ll happily pay if the content is good, but just letting me see the preface, contents, index and maybe a few pages of chapter 1 isn’t enough for me to discern that. Libgen at least lets me see what I might be getting. Libgen is also great for books that are long out of print, and the authors long dead. It’s a crime against humanity that these works are locked up by our archaic copyright laws, for things that have long since ceased to be remotely profitable for the publisher.
