We focused our attention on the exhaustive study of the elements of corporate visual identity projected through Internet by Spanish university libraries. We have started from the fact that corporate personality or public personality corresponds to the intentional image that an organization tries to show to the public; everything is directed towards this purpose and prepared and calculated to get a good result. The methodology entailed, firstly, locating and analyzing the websites of the Spanish university libraries, and then identifying the elements of the corporate visual identity. These elements would be the ones included in the program of corporate visual identity. Once all the libraries were analyzed, and after verifying which elements of the corporate identity are present in each library, we made a study focused on the definition and classification of the forms and styles of corporate visual identity that predominate in the Spanish university libraries.
