Has Anyone Found Reliable Alternatives to FreeBookSpot for Free eBook Downloads?

Thanks for all the suggestions, guys! I checked out Z-Library and PDF Drive, and they’re both awesome.

Z-Library’s daily limit is a bit annoying, but the selection is insane. PDF Drive is super easy to use, and no pop-ups, which is a huge plus.

Still gonna try out LibGen and Open Library later this week. Appreciate the help!
