What the library is
Library lists ebooks you own on Kadoverse. Titles stay available to re-open; you are not renting them month-to-month.
Opening a book
Choose a book from Library to open the reader. Navigation depends on how the author structured the book (pages, sections, images).
Progress
When you are signed in, reading position can be tied to your account so you can continue on another browser or device after signing in again. If you read without an account, progress may only exist on that device until you create or sign in to an account with the same email used at purchase.
PDFs
Some books include a PDF download. You may also upload your own PDFs under My PDFs—those are separate from store purchases.
