?Where should I check the edition and download format?
Open the linked book source and confirm the edition and available format there. A listing may point to a reading page rather than a downloadable file.
?Can I redistribute a book found in this library?
Do not assume so. Check the source license or permission before sharing a copy; sharing the listing link and redistributing the book are different actions.
