May be a silly question, but help a breh out, but how the hell do you download the book
1. Search for your book
2. Click the "title" of the book and file "extension" (name of column towards the right) that you want.
3. This will take you to the book's main page. Click on the title link again.
4. This will take you to a page asking to take you to the download page. Click it.
5. Download.
Libgen has several sites that it uses to keep the heat off, meaning the process will look slightly different depending on the site you're using or book you are getting.
You just need to feel your way around until you reach the download page. Best way to get there is to keep clicking on the book title and following along.
