Performing actions based on capturing information from rendered documents, such as documents under copyright
View Patent ↗A hardware, firmware, and/or software facility (“facility”) for providing information relevant to rendered documents is described. In some embodiments, the facility identifies multiple versions of an electronic document corresponding to a rendered document captured by a capture device. The facility may then provide a person utilizing the capture device with various ways to interact with one or more versions of the electronic document. In some embodiments, the facility determines that use of a rendered document is restricted, such as by copyright, to some degree. The facility may then offer the person the option to obtain unrestricted use of the rendered document. If the person accepts, the person obtains the right to store captures of the rendered document. If the person declines, the facility automatically discards captures of the rendered document. In some embodiments, the facility may automatically purchase rights to restricted-use rendered documents based upon the person's predefined criteria.

8. The method of claim 1 , further comprising:
receiving an image of a second portion of the document;
identifying a second location in the second version of the electronic document corresponding to a location of the second portion in the document; and
providing data that cause presentation of a second portion of the second version of the electronic document that corresponds to the second location.
9. The method of claim 1 , further comprising:
receiving a request for a change notification related to a portion of at least one of the first version of the electronic document and the second version of the electronic document;
after receiving the request, identifying a modification to the portion of at least one of the first version of the electronic document and the second version of the electronic document; and
after identifying the modification, providing the change notification.
10. A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:
receiving an image of a portion of a document that was captured by a first user using a camera, wherein the image includes text;
identifying an electronic document that includes the text;
determining, by the one or more computing devices, that there are a plurality of versions related to the identified electronic document, wherein the plurality of versions of the electronic document include a first version that corresponds to the document and a second version that differs from the first version; and
providing, in response to the determination, data that present document information informing the first user of the plurality of versions of the electronic document together with information identifying, to the first user, a second user that is currently reading a most recent version of the document.
11. The non-transitory computer-readable storage medium of claim 10 , wherein the second version of the electronic document is derived from the first version of the electronic document.
12. The non-transitory computer-readable storage medium of claim 10 , wherein each of the first version of the electronic document and the second version of the electronic document is derived from a third version of the electronic document, and wherein the third version of the electronic document differs from each of the first version of the electronic document and the second version of the electronic document.
13. The non-transitory computer-readable storage medium of claim 10 , wherein the first version of the electronic document corresponds to a first publication of the electronic document and the second version of the electronic document corresponds to a second publication of the electronic document.
14. The non-transitory computer-readable storage medium of claim 10 , the operations further comprising:
identifying a difference between the first version of the electronic document and the second version of the electronic document; and
providing an indication of the identified difference.
15. The non-transitory computer-readable storage medium of claim 10 , the operations further comprising:
receiving a request to print a portion of at least one of the first version of the electronic document and the second version of the electronic document; and
causing the portion of at least one of the first version of the electronic document and second version of the electronic document to be printed based on the request.
16. The non-transitory computer-readable storage medium of claim 10 , the operations further comprising:
identifying a location in the second version of the electronic document corresponding to a location of the portion of the document that is in the image; and
providing data that cause presentation of a portion of the second version of the electronic document that corresponds to the identified location.
17. The non-transitory computer-readable storage medium of claim 16 , the operations further comprising:
receiving an image of a second portion of the document;
identifying a second location in the second version of the electronic document corresponding to a location of the second portion of the document; and
providing data that cause presentation of a second portion of the second version of the electronic document that corresponds to the second location.
18. The non-transitory computer-readable storage medium of claim 16 , further comprising:
receiving a request for a change notification related to a portion of at least one of the first version of the electronic document and second version of the electronic document;
after receiving the request, identifying a modification to the portion of at least one of the first version of the electronic document and the second version of the electronic document; and
after identifying the modification, providing the change notification.
19. A method, comprising:
receiving, by one or more computing devices, an image of a portion of a document that was captured by a first user using a camera, wherein the image includes text;
identifying, by the one or more computing devices, an electronic document that includes the text;
receiving, by the one or more computing devices, a request for a change notification related to content of the electronic document;
after receiving the request, determining, by the one or more computing devices, that the portion of the electronic document was modified; and
