Abstract

The present invention is a system and method for providing access to electronic works over a network. In a preferred embodiment, the present invention offers a user access to electronic copies of works, such as songs, albums, movies, or music videos, over a network. The user responds to the offer by requesting to access to a particular work. Before such a request is granted, the present invention may verify that the user is authorized to access to the work. In one embodiment, the user verifies that they are authorized to access an electronic copy of the work by demonstrating that they possess a physical copy of the work. In another embodiment, the user verifies that they are authorized to access an electronic copy of the work by demonstrating that they ordered or purchased a copy of the work. If a user'"'"'s authorization is verified, the user may then be provided with access to an electronic copy of the work by such techniques as downloading or streaming.

18. The method of claim 16, wherein the step of extracting further extracts index information.

19. The method of claim 18, wherein the index information identifies what samples of the physical work were extracted.

20. The method of claim 16, further comprising the step of:

labeling the physical work.

21. The method of claim 20, wherein the physical work is labeled with a UPC code.

22. The method of claim 16, further comprising the step of:

labeling the electronic work with a label corresponding to the label on the physical work.

23. The method of claim 16, further comprising the steps of:

labeling the electronic work; and
