Abstract

A system and method for preparing and searching a user-personalized library of content includes preparing a general library comprised of images of pages of content and electronically-searchable text corresponding to the text in the page images, which is then personalized by receiving from the user a selection of the content to include in the user'"'"'s personalized library. User selection of content for a personalized library may be accomplished manually or automatically as a result of user actions, such as user review or purchase of content. Preferably, full text searching of the content in the user'"'"'s personalized library is enabled. Page images in the personalized library containing text that match the user'"'"'s search terms are provided to the user for display. Highlighting of search terms in page images by a user device and access rules that act to limit the viewing of content are further provided.

Claims

1. A method for electronically searching a user-personalized library of content, comprising:

(a) receiving one or more search terms from a user having an electronically-searchable personalized library of content, the personalized library including a text searchable database and a page image database;

(b) electronically searching the text searchable database for pages of content that match the search terms to produce search results;

(c) providing the search results to the user;

(d) receiving a search result selection from the user;

(e) preparing a substitute image of a page image in the page image database corresponding to the search result selection from the user, wherein a portion of the content in the page image is suppressed in the substitute image in accordance with one or more access rules to limit the amount of content in the substitute image;

(f) providing location information to the user that identifies the location of the search terms in the substitute image; and

(g) providing to the user the substitute image responsive to the user'"'"'s search result selection such that a portion of the content in the page image is suppressed in the substitute image provided to the user with an instruction to highlight the search terms in the substitute image, wherein the instruction to highlight the search terms in the substitute image comprises an instruction to apply a layer of color on or near the search terms.

2. The method of claim 1, further comprising, prior to receiving one or more search terms from the user, establishing an electronically-searchable library of content that includes a page image database and a text searchable database, which library of content is personalized by the user to consist of content selected by the user.

3. The method of claim 2, in which the library of content is personalized by manual selection of content by the user.

4. The method of claim 2, in which the library of content is automatically personalized based on user selection of content for review or purchase.

5. The method of claim 2, in which a non-text object in the user'"'"'s personalized library is made searchable by including text data related to the object in the text searchable database.

6. The method of claim 1, in which the user-personalized library of content is established at the time the user conducts the search.

7. The method of claim 1, in which the user'"'"'s personalized library of content is derived from a publicly-accessible general library of content.

9. The method of claim 8, further comprising ranking the content in the list of content according to a predetermined criterion.

10. The method of claim 1, in which providing to the user an image of a page of content includes retrieving the page image from a database of page images stored in computer memory.

11. The method of claim 1, in which the user'"'"'s personalized library is defined after electronically searching a general library of content using the search terms, the user'"'"'s personalized library being fully contained within the general library of content and defining the scope of search results provided to the user.

12. The method of claim 1, wherein the instruction to highlight the search terms in the substitute image comprises one of an instruction to apply a layer of color on or near the search terms or an instruction to place a visual indicator next to the search terms.

13. The method of claim 1, in which the access rules define an aggregate amount of unsuppressed content that can be provided to the user over a time frame.

14. The method of claim 1, in which the access rules define a percentage of unsuppressed content that can be provided to the user over a time frame.

15. The method of claim 1, in which the access rules define the amount of unsuppressed content that can be provided to the user based on content-specific information.

16. The method of claim 1, in which the access rules define the amount of unsuppressed content that can be provided to the user based on user ownership of the content.

17. The method of claim 16, further comprising reviewing purchase records to validate user ownership of the content.

18. The method of claim 1, in which different access rules apply based on the location of the user.

19. The method of claim 1, in which different access rules apply based on the time the content is to be provided to the user.

20. The method of claim 1, in which the access rules define the amount of content that can be provided to the user based on an identification of the user.

21. A method for preparing a user-personalized library of content for electronic searching and delivery of content to a user, comprising:

(a) acquiring a general library of content that includes images and corresponding text of pages of content;

(b) preparing a page image database comprised of the images of pages of content;

(c) preparing a text searchable database comprised of the corresponding text of pages of content;

(d) receiving from a user a selection of content in the general library to form a user-personalized library of content that the user can electronically search using the text searchable database;

(e) identifying an image of a page of content in the page image database based on a search of the text searchable database;

(f) preparing a substitute image of the identified image, wherein the substitute image is modified from the appearance of the identified image to automatically suppress a portion of content of the identified image in accordance with one or more access rules to limit the amount of content in the identified image, such that when the substitute image is displayed, a portion of the content in the identified image is suppressed in the substitute image; and

(g) defining classes of content and assigning content in the user'"'"'s personalized library to one or more of the classes, and limiting a search of the user'"'"'s personalized library to content in a specified class.

22. The method of claim 21, in which the personalized library of content is comprised of content selected by a group of persons constituting a user, the method further comprising enabling persons in the group to conduct searches of the personalized library of content.

23. The method of claim 21, in which the user'"'"'s selection of content in the general library is received based on manual selection by the user.

24. The method of claim 21, in which the user'"'"'s selection of content in the general library is automatically received based on the user'"'"'s review or purchase of the content.
