Comunicación corporativa de organizaciones que ofrecen recursos bibliotecarios en la Web.

We analyze the online corporate communications of 17 institutions of the library and information science area, selected from those contained in the Anuario de bibliotecas españolas 2009 (Spanish libraries yearbook) of the Fundación Alonso Quijano. We analyze the management and communication effectiveness of the brands present on their portals, based on a model designed for this purpose. Online communication options affect the image and reputation of companies and, therefore, it is essential to take care of them. [ABSTRACT FROM AUTHOR]
