Hemerotecas de prensa digital. Evolución y tendencias

This paper analyses the digital press archives of the Spanish newspapers with the largest digital circulations. This is an evaluative study based on twenty seven indicators divided into four main sections: general features, contents, the query system, and presentation of results. We present the results of an analysis conducted in 2010, and relate to those obtained previously in 2007. The article points out the best and worst aspects of the digital press archives, establishing a ranking of newspapers in which El mundo, Abc, El país and La vanguardia occupy the top positions, and finally shows five major trends: extension of the temporary fund online, free archives versus payment archives, simplification (and depletion) of the query, filters in the presentation of results and documentary products in the archive section
