Methods and systems for receiving and distributing annotations of a digital work include receiving an annotation of the digital work, storing the annotation, and providing the annotation to a user. The user may be required to submit a valid authorization credential for the annotation. Annotations may be textual or graphical, and may be associated with particular content in a digital work. Indicators may be displayed to identify content in the digital work for which annotations are available. A user may exchange compensation or perform a specified action for access to an annotation. Some or all of the compensation received for an annotation may be distributed to the author of the annotation. Multiple annotations may be listed in an order based a criterion, such as ranking, price, or date of receipt. Users that purchase a digital work may automatically receive an authorization credential to receive annotations of the digital work.

A non-transitory computer-readable medium having stored thereon computer-executable instructions that, in response to execution by a computing system, cause the computing system to: receive from a client system an annotation of a digital work by a first user;store the annotation in a memory in association with the digital work;require a second user desiring to access the annotation of the first user to perform a specified action before providing an authorization credential to the second user, wherein the specified action is contributing an annotation of a digital work; andupon receipt of the authorization credential from the second user desiring to access the annotation, provide the annotation to a client system for output to the second user, wherein the annotation is provided in context with regard to the digital work. 24. The computer-readable medium of claim 23, further configured with program instructions that direct the computing system to receive the annotation in a graphical format. 25. The computer-readable medium of claim 23, further having stored thereon computer-executable instructions that direct the computing system to receive the annotation in a textual format. 26. The computer-readable medium of claim 23, further having stored thereon computer-executable instructions that direct the computing system to store the annotation in association with particular content in the digital work. 27. The computer-readable medium of claim 23, further having stored thereon computer-executable instructions that direct the computing system to receive the annotation in the form of an image. 28.
