The first is the simple and obvious one of recataloguing every book entered in the Alphabetical Catalogue in the briefest possible form, and breaking up these titles into sections, according to subject, the alphabetical order being still preserved in each. Thus Simson's "History of the Gipsies" would be found in the General Catalogue entered at length, and again in an abridged form in a special index of books relating to the Gipsies, which would refer the reader to the General Catalogue.
