"Digital technologies are changing both how library materials are accessed and increasingly how library materials are preserved. After the Internet Archive digitizes a book from a library in order to provide free public access to people world-wide, these books go back on the shelves of the library. We noticed an increasing number of books from these libraries moving to “off site repositories” to make space in central buildings for more meeting spaces and work spaces. These repositories have filled quickly and sometimes prompt the de-accessioning of books. A library that would prefer to not be named was found to be thinning their collections and throwing out books based on what had been digitized by Google. While we understand the need to manage physical holdings, we believe this should be done thoughtfully and well." Read more: Why preserve books? The Physical Archive of the Internet Archive.
