We are no longer able to take unsolicited donations of books or other library materials. While we have been fortunate over our long history to receive many valuable gifts, the current size and extent of our collections means that the very great majority of unsolicited gifts duplicate our current holdings. The process of reviewing and sifting through gifts is time-consuming and costly.
If you have a book you think we should add to our collection, please complete the purchase request form.
For other ways to give to Harvard Library, please see this page on supporting the library.
