at a centralized electronic resource system, obtaining metadata about one or more electronic library resources from a plurality of different library resource publishers, the metadata defining locations of the electronic library resources;

at the centralized electronic resource system, normalizing the metadata to a standardized format appropriate for a plurality of library resource systems;

at the centralized electronic resource system, providing a user with a consistent interface to show the user content available from the plurality of different library resource publishers regardless of the publisher actually having a particular resource;

at the centralized electronic resource system, receiving a request from the user at the consistent interface for the one or more electronic resources, wherein the request is in a format appropriate for the centralized electronic resource system, but not appropriate for the publisher having the one or more electronic library resources;

at the centralized electronic resource system, converting the request from the user to a format and protocol appropriate for the publisher having the one or more electronic library resources;

at the centralized electronic resource system using the converted request, obtaining the one or more electronic library resources; and

the centralized electronic resource system providing the one or more electronic library resources to the user.

2. The method of claim 1 further comprising creating a super catalog of electronic library resources based on the normalized metadata.

3. The method of claim 2 , wherein the resource systems request electronic resources against the super catalog.

4. The method of claim 1 further comprising publishing the normalized metadata to the library resource systems.

5. The method of claim 1 further comprising receiving from one or more resource systems, one or more requests for electronic library resources, wherein the requests are based on the normalized metadata.

6. The method of claim 1 further comprising retrieving the one or more electronic resources from the publisher and providing the one or more electronic resources to a patron exclusive of the publisher providing the one or more electronic resources directly to the patron.

7. The method of claim 6 , wherein retrieving comprises retrieving in a plurality of versions of the one or more electronic resources.

8. The method of claim 7 wherein each of the versions of the one or more electronic resources comprises their own use restriction requirements.

9. The method of claim 7 further comprising storing the plurality of versions of the one or more electronic resources and associating the plurality of versions with a particular customer.

10. The method of claim 7 further comprising storing the plurality of versions of the one or more electronic resources and associating the plurality of versions with a particular patron.

11. The method of claim 7 further comprising storing a bookmark for each of the versions specifying a bookmarked location within the one or more electronic resources.

12. The method of claim 11 , wherein the bookmarked location is specified through a drop box.

13. The method of claim 12 , wherein the drop box is user specified.

14. The method of claim 12 , wherein the drop box is a system handled API based drop box.

15. The method of claim 1 further comprising determining if the one or more electronic resources are available by querying one or more publishers.

16. The method of claim 15 wherein querying comprises determining real time availability of the one or more electronic resources.

17. The method of claim 15 wherein querying comprises specifying a customer identifier and receiving availability of the one or more electronic resources based on customer identifier.

19. The method of claim 1 further comprising obtaining full text of the one or more electronic resources with the metadata and storing the full text associated with the metadata.

20. A system for providing electronic library resources, the system comprising:

one or more processors; and

one or more computer readable media comprising computer executable instructions that when executed by the one or more processors cause the system to perform the following:

at a centralized electronic resource system, obtaining metadata about one or more electronic library resources from a plurality of different library resource publishers, the metadata defining locations of the electronic library resources;

at the centralized electronic resource system, normalizing the metadata to a standardized format appropriate for a plurality of library resource systems;

at the centralized electronic resource system, providing a user with a consistent interface to show the user content available from the plurality of different library resource publishers regardless of the publisher actually having a particular resource;

at the centralized electronic resource system, receiving a request from the user at the consistent interface for the one or more electronic resources, wherein the request is in a format appropriate for the centralized electronic resource system, but not appropriate for the publisher having the one or more electronic library resources;

at the centralized electronic resource system, converting the request from the user to a format and protocol appropriate for the publisher having the one or more electronic library resources;

at the centralized electronic resource system using the converted request, obtaining the one or more electronic library resources; and

the centralized electronic resource system providing the one or more electronic library resources to the user.
