This article presents the results of a study of academic e-books that compared the metadata and search results from major academic e-book platforms. The authors collected data and performed a series of test searches designed to produce the same result regardless of platform. Testing, however, revealed metadata-related errors and significant variation in search results that could impact the user experience. This article describes how other libraries could perform this type of testing and how this information could be used to inform the selection of e-books that are available on multiple platforms.
