basically, find a book on archive.org and then borrow it for an hour or something

then, paste the link in here and you'll download a file from the new created tab

open with Adobe Digital Editions and let it fully load in

get Calibre 4.23 and also download deDRM. Make sure to unzip it once.

open Calibre and navigate to the preferences page (click the 3 dots on the side menu since it likely won't show up unless you're full screen or something

go to plugins in the advanced tab and load from file, then find your DeDRM_Plugin.zip file to accept it

once setup is done, go to your documents folder and into "My Digital Editions" folder

drag the pdf files you want individually into an open calibre window so that it's added to the library

just right click in the library to "open containing folder" or something like that and boom, that's your pdf. make sure to copy it out of the folder though into another place

Note: home computer only, not chromebook - ask for assistance in person if needed

if you got an error for the download link, make sure you borrowed it already.

also, if your final pdf isn't opening in a web browser properly, then your de-drm process went wrong somewhere and you can try adding it to the library fresh again from "My Digital Editions"
