If you own books printed in the Ukrainian language (or Russian or English), you may be interested in this article published in the Internet Archive Blog:
The Internet Archive is requesting donations of Ukrainian books and books useful to Ukrainians. The books will be preserved, digitized and lent (for free to one user at a time) over the Internet. The Internet Archive is prioritizing the digitization and hosting of relevant materials for Ukrainians.
Already the University of Toronto and University of Alberta has sponsored the digitization of sizable Ukrainian collections, where the total collections on archive.org total over 8,000 items in Ukrainian.
But we need much more to support Ukrainians, many of whom are displaced and do not have access to their schools and libraries.
We need your help. Together we can preserve all published works and make them as widely available as we can.
The Internet Archive provides free downloading of public domain materials, services for those with print disabilities, free Controlled Digital Lending of books, free interlibrary loan services, free hosting for materials that are uploaded to archive.org, and supports web archiving efforts. These services can be more relevant to Ukrainians with your help.
