An extensive description of José Donoso's early notebooks — those numbered A-F, 1-14, and 33 and housed in boxes 5-7 and 9 — was compiled by Maria Laura Bocaz in July 2007 and, lightly edited, appears below.

Notebooks numbered 15-32 primarily detail the composition of El Obsceno Pájaro de la Noche. They were investigated by Bocaz in summer 2008, with the results used in her doctoral disseration (2010) and, again lightly edited, appear below.

Literary rights to Donoso's work is held by his estate and administered by his daughter, Pilar Donoso.
