Black opals.

A curated selection of books entering the public domain starting in the year 2020 (or those published in 1924) that have been chosen by the librarians in the Special Collections Department at Princeton’s Firestone Library. All of these books were important milestones in literature, although only two each year have been recognized as canonical within a North American literary landscape. The others celebrate the narratives of women, Queer, and/or people of color to challenge and expand notions of the canon.
