This paper presents an evaluation of the Spanish journals specialized in History, collected at the CSIC's database ISOC. The analysis applies a new categorization system, still in an experimental stage, designed as a byproduct of this bibliographic resource. In the ranking obtained the most outstanding publications are Historia Actual Online, Imago Temporis, Revista de Historia Actual and Revista de Historia Económica. From the results of this categorization, the paper analyzes the prevailing editorial features, the distribution of authorship, its thematic profile and the different variables that influence on the quality of the journals.
