9. A method comprising: inputting a plurality of digital catalogs of products or services; extracting content from the plurality of digital catalogs; classifying and indexing the extracted content according to a taxonomy that is specific to a particular industry, said particular industry being an industry other than electronic catalogs; storing the extracted content in a database in a computer system in accordance with said taxonomy, wherein said storing includes generating and storing a hierarchy of unique objects to represent each of the plurality of digital catalogs, and wherein said generating includes defining, for each catalog of the plurality of digital catalogs, a parent object to store a front page of the catalog, related catalog data and a pointer to each child object of the parent object, and a child object of the parent object to represent an internal page of the catalog, the child object including content of the internal page, a page number of the internal page, and a pointer to the parent object; uploading a user-provided logo at the computer system; associating the logo with at least one catalog of the plurality of digital catalogs at the computer system, in such a manner that when a user views a result set corresponding to a search, the logo will be superimposed on an image associated with the at least one catalog in the result set; receiving from a user a search query via a network; and in response to the search query, identifying, by the computer system, content extracted from one of the digital catalogs and stored in the database, which satisfies the search query; identifying, by the computer system, a particular page of said one of the digital catalogs from which the identified content was extracted; and sending the result set over the network to cause the result set to be output to the user, the result set including, in association with each other, the identified content extracted from said one of the digital catalogs and stored in the database, which satisfies the search query, and an image of the particular page of said one of the digital catalogs from which the identified content was extracted.
