If you have a title you wish to be bought for your Onleihe please contact your library. You can contact your library at any time via email if you click the "Contact"- button on your Onleihe-Website. We recommend that you provide your library with more then a book title. Additional information such as: author, publisher, and the ISBN help the personnel with acquiring the title.
Not every book by every publisher can be bought by your library, because not every publisher makes their eBooks available for borrowing.
Additionally some publishers may make new releases only available to libraries after a certain period. This period can vary and last up to 6 month.
