Princeton University Press is an established academic press with excellent distribution.
Not only are they currently open to proposals but they just started a Supporting Diverse Voices Development Grant hoping to support historically excluded scholars from around the world with the grant. This is how the grant will work: “In close partnership with four book coaches, the grant will offer direct support and coaching to scholarly authors preparing to draft a book proposal. The grant will cover all associated costs of this process, with grantees able to select which coach they wish to partner with.”
The first round of funding is focusing on Women, transgender, and gender expansive authors in Science and Mathematics. It opened for submissions from February 15th and will run until April 1st.
