摘要:
Search may be performed on a user device (104), such as a handheld electronic book reader device. A search query term may be received (6902, 7002). Text of a collection of electronic items stored in memory of the user device may be searched (6912, 7004) for the queried term. Search results may be returned (7014) identifying locations in the electronic items at which the queried term appears.

A method of presenting a digital work includes displaying a portion of the digital work on a display screen (100) under a set of display conditions, and providing one or more invariant location reference identifiers (300) corresponding to the portion of the digital work on the display screen. The invariant location reference identifiers (300) are separate from the digital work, and each invariant location reference identifier is provided along with the corresponding portion of the digital work, regardless of the display conditions under which the portion of the digital work is displayed.

摘要:
Search may be performed on a user device (104), such as a handheld electronic reader device. In that case, when a search query is received (6902), a determination (6906) can be made to search one or more available sources of content for the query term. Available sources of content may include at least one local source of content and at least one remote source of content.
摘要:
A digital work may be annotated using an eBook reader device. Upon receiving an annotation relating to a specific portion of the digital work, an invariant location reference identifier corresponding to the specified portion of the digital work may be appended to the annotation. The annotation may then be stored in association with the digital work for later reference. In some instances, an annotation may be presented on an eBook reader device upon receipt of a valid authorization credential granting access to the annotation.
