Abstract
Techniques for aligning content items with one another are described herein. These techniques may align different versions of a same content item for the purpose of identifying differences between the versions, identifying commonalities between the versions, mapping annotations made in one version to the other version, aggregating annotations across the different versions, or for any other reason. The content items may include electronic books, songs, videos, documents, or the like.
