Antonio Saura's body of painted works was discussed by the artist himself in his writing, where he defined and listed the various themes that went into it. This exercise took the form of a register kept by the artist and which served as the basis for establishing the catalogue raisonné of his painting. Published for the first time in 1992 under the title Note book (memoria del tiempo), this register was given a revised, enlarged, and illustrated edition in 2009 under the title Antonio Saura par lui-même.
