Vendors frequently push the advantages of buying e-books instead of print books. There are many advantages, but three specific ones come to mind. First, an e-book can be accessed remotely (depending on license restrictions) and can therefore make a single purchase available in multiple office locations, school buildings, or even at trial or at home. Second, e-books allow the library to devote space to other amenities like study carrels or office space. Third, their use makes the library seem technologically progressive. But are librarians and vendors also aware of the cognitive disadvantages of e-books?
