Handwritten library catalog of Pedro Nuñez de Guzmán, 3rd Marques de Montealegre, who flourished around 1668. Incomplete, apparently volume 1 of 2. It ends with equivalent of leaf 132 verso of the printed version. Either copied from printed version or from a common source, this volume does not include a title-page (in Spanish) of printed version or its preface, or table of headings, or the addena (Diferencia) printed at the end of part 2.
