Transiting Pop art, Feminist Expressionism, Conceptualism and Minimalism, Lee Lozano (1930-1999) sits alongside Eva Hesse and Hannah Wilke as a radical and influential model for younger generations of female artists. Lozano's notebooks, which she approached as drawings, and which were later dismantled and sold as individual pages, became a part of her artmaking at the height of her fame in the late 1960s. Reproduced here for the first time, as an affordably-priced facsimile reprint, the three notebooks collected here, which were kept between 1967-1970, contain sketches for her Wave paintings, writings about the trajectory of her artistic process and the language pieces that she became famous for prior to her withdrawal from the art world. They thus constitute the fullest and richest document on an artist whose relevance and profile have recently seen a steady ascent.
