I have uploaded over 160 English language learning books to a Google drive account named ELibraryBud, a resource I created for students when I was teaching in Budapest, Hungary.
Anyone can view and download books from this link. If you use the grid view, it may look like there are multiple copies of the same title. However, in the list view, you will see they may be the same publisher, but vol. 1, 2 or something different with each.
Questions or problems, send me an email to firstname.lastname@example.org
