Establishing an interactive environment for rendered documents
A system for identifying an electronic counterpart for a rendered document is described. The system receives an indication of a text capture operation performed from a rendered document. The indication identifies a text sequence captured as part of the text capture operation, the identified text sequence comprising fewer than nine words. In response to receiving the indication, the system uniquely identifies an electronic document from which the rendered document was rendered.

5. The method of claim 1 , further comprising determining that a user that caused the phrase to be captured is not registered to access the identified supplemental electronic materials, wherein enabling access to the identified supplemental electronic materials comprises permitting partial access to the identified supplemental electronic materials in response to determining that the user is not registered to access the identified supplemental electronic materials.
6. The method of claim 1 , further comprising determining that print version of the document is registered for accessing the identified supplemental electronic materials, wherein enabling access to the identified supplemental electronic materials comprises permitting full access to the identified supplemental electronic materials in response to determining that the print version of the document is registered for accessing the identified supplemental electronic materials.
7. The method of claim 1 , wherein determining that the request to access the supplemental electronic materials associated with the document is implicit in the phrase comprises determining that a user has interest in the supplemental electronic materials based on previous content related to the supplemental electronic materials that has been scanned by the user.
8. A system, comprising:
a data processing apparatus; and
a memory storage apparatus in data communication with the data processing apparatus, the memory storage apparatus storing instructions executable by the data processing apparatus and that upon such execution cause the data processing apparatus to perform operations comprising:
receiving (i) a phrase captured from a print version of a document, and (ii) an indication that the phrase was captured from the print version of the document;
identifying the document using the phrase;
determining that a request to access supplemental electronic materials associated with the document is implicit in the phrase;
identifying the supplemental electronic materials associated with the document in response to determining that the request to access supplemental electronic materials is implicit in the phrase;
requesting that the user scan content that is located at a particular location within the print version of the document to receive access to the identified supplemental electronic materials;
receiving data specifying scanned content;
determining that the scanned content matches the content that is located at the particular location within the print version of the document;
determining that the request satisfies a set of one or more access rules for the identified supplemental electronic materials based on the indication that the phrase was captured from the print version of the document and (ii) the scanned content matching the content that is located at the particular location within the print version of the document; and
providing the identified supplemental electronic materials for output in response to determining that the request satisfies the set of access rules.
9. The system of claim 8 , wherein:
the set of one or more access rules specifies one or more geographic locations in which the identified supplemental electronic materials are accessible; and
determining that the request satisfies the set of one or more access rules comprises determining that a geographic location at which the phrase was captured matches at least one of the one or more geographic locations specified by the set of one or more access rules.
10. The system of claim 8 , wherein:
the set of one or more access rules specifies one or more time periods in which the supplemental electronic materials are accessible; and
determining that the request satisfies the set of one or more access rules comprises determining that a time at which the phrase was captured matches at least one of the one or more time periods specified by the set of one or more access rules.
11. The system of claim 8 , wherein the instructions upon execution cause the data processing apparatus to perform further operations comprising determining that a user that caused the phrase to be captured is registered to access the identified supplemental electronic materials, wherein enabling access to the identified supplemental electronic materials comprises permitting full access to the identified supplemental electronic materials in response to determining that the user is registered to access the identified supplemental electronic materials.
12. The system of claim 8 , wherein the instructions upon execution cause the data processing apparatus to perform further operations comprising determining that a user that caused the phrase to be captured is not registered to access the identified supplemental electronic materials, wherein enabling access to the identified supplemental electronic materials comprises permitting partial access to the identified supplemental electronic materials in response to determining that the user is not registered to access the identified supplemental electronic materials.
13. The system of claim 8 , wherein the instructions upon execution cause the data processing apparatus to perform further operations comprising determining that print version of the document is registered for accessing the identified supplemental electronic materials, wherein enabling access to the identified supplemental electronic materials comprises permitting full access to the identified supplemental electronic materials in response to determining that the print version of the document is registered for accessing the identified supplemental electronic materials.
14. The system of claim 8 , wherein the request to access the supplemental electronic materials associated with the document is implicit in the phrase comprises determining that a user has interest in the supplemental electronic materials based on previous content related to the supplemental electronic materials that has been scanned by the user.
15. A computer storage medium encoded with a computer program, the program comprising instructions that when executed by a data processing apparatus cause the data processing apparatus to perform operations comprising:
receiving (i) a phrase captured from a print version of a document, and (ii) an indication that the phrase was captured from the print version of the document;
identifying the document using the phrase;
determining that a request to access supplemental electronic materials associated with the document is implicit in the phrase;
identifying the supplemental electronic materials associated with the document in response to determining that the request to access supplemental electronic materials is implicit in the phrase;
requesting that the user scan content that is located at a particular location within the print version of the document to receive access to the identified supplemental electronic materials;
receiving data specifying scanned content;
determining that the scanned content matches the content that is located at the particular location within the print version of the document;
determining that the request satisfies a set of one or more access rules for the identified supplemental electronic materials based on (i) the indication that the phrase was captured from the print version of the document and (ii) the scanned content matching the content that is located at the particular location within the print version of the document; and
