How do I upload books?
If you want to upload up to 50 books, use our standard web uploader. For bulk upload you should request FTP access on the same page.
I can’t find a specific book in Z-library. Can I ask you to add such a specific book?
Yes, you can request a specific book using the Book Request option. Book request doesn’t guarantee that the book will be added, but it helps our community members add the most requested books sooner. Please note that this option is available only for books with ISBN. Books without ISBN can be tracked using the Z-Alerts.
I can download books, but I can’t download articles (or I can download articles but not books).

Can I send books directly to my Kindle device?
Yes, you can! To set up the send-to-Kindle option, please follow this instruction.
I can’t download any book! The system says my IP address has already reached the download limit.
We recommend creating an account and sign in to avoid this problem. If you did not sign in, download limits are calculated based on your device IP address. It’s common practice for Internet providers to use shared IP addresses for multiple devices, in which case the download limit is also shared between these devices.
How many books can I download through the Telegram bot?
You can download extra books in addition to your daily limit on the website. For example, if you have a daily limit of 10 books and have already used it, you can get an additional 10 downloads through the bot (20 daily downloads in total). Or you can only use the bot and download 20 books from there.
