A computer-implemented method serves electronic document information in response to a user query identifying a target electronic document. The user query prompts a library search of library-stored electronic documents to determine whether the target electronic document corresponds to a library-stored electronic document. When the target electronic document corresponds to a library-stored electronic document, the library-stored electronic document is presented for review by the user. Also presented is information associated with the relationship between the library-stored electronic document and the target electronic document. In some embodiments, if the target electronic document does not correspond to the library-stored electronic documents, the method includes providing-link information for user access to the target web page.
