Providing supplemental information for a digital work in a user interface

A system comprising:

• one or more processors;
• and
• non-transitory computer-readable media having instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• presenting a digital work on a display;
• receiving an indication of a selection of an object of objects associated with the digital work;
• and
• at least partly in response to the receiving of the indication of the selection of the object, presenting a user interface, the user interface including:
• visual representations corresponding to the objects associated with a series of digital works that includes the digital work, individual digital works of the digital works in the series having an individual publication date and title, each of the visual representations including an identifier of one of the objects and one or more indications of location or frequency of occurrence of the object with respect to the series of the digital works;
• and
• a bar overlaid on at least a portion of the visual representations corresponding to the one or more indications, a first location of the bar indicating a selected digital work in the series, the selected digital work distinguished from other digital works in the series, a first width of the bar at the first location corresponding to a first size of the selected digital work as compared to an overall size of the series of the digital works, and
• wherein the bar includes a navigational element to allow navigation of the bar to a second location indicating an additional digital work in the series, the additional work distinguished from the other digital works in the series, a second width of the bar at the second location corresponding to a second size of the additional digital work as compared to the overall size of the series of the digital works.

A method comprising:

• under control of one or more processors of an electronic device specifically configured with executable instructions,
• presenting a digital work including objects;
• receiving a selection of an object of the objects, the object including at least one of a word or phrase selected from the digital work;
• and
• at least partly in response to the receiving of the selection of the object, presenting a user interface, the user interface including:
• a visual representation including an identifier of the object and one or more indications of location or frequency of occurrence of the object in the digital work in proportion to a total length of a series of digital works that includes the digital work, individual digital works of the digital works in the series having an individual publication date and title;
• and
• a graphic element overlaid on at least a portion of the visual representation, a first location of the graphic element indicating a selected digital work in the series, the selected digital work distinguished from other digital works in the series, a first expanse of the graphic element at the first location indicating a first proportion between a first length of the digital work as compared to an overall length of the series of the digital works, and
• wherein the graphic element includes a navigational element to allow navigation of the graphic element to a second location indicating an additional digital work in the series, the additional digital work distinguished from the other digital works in the series, a second expanse of the graphic element at the second location indicating a second proportion between a second length of the additional digital work as compared to the overall length of the series of the digital works.
