An electronic marketplace for used digital objects is disclosed. Digital objects including e-books, audio, video, computer applications, etc., purchased from an original vendor by a user are stored in a user's personalized data store. Content in a personalized data store may be accessible to the user via transfer such as moving, streaming, or download. When the user no longer desires to retain the right to access the now-used digital content, the user may move the used digital content to another user's personalized data store when permissible and the used digital content is deleted from the originating user's personalized data store. When a digital object exceeds a threshold number of moves or downloads, the ability to move may be deemed impermissible and suspended or terminated. Additionally or alternatively, a collection of objects may be assembled from individual digital objects stored in the personalized data stores of different users, and moved to a user's personalized data store.
