When making comps to manuscripts you are submitting, here’s a great resource. The 2020 list of Bank Street College’s award winning books. Below is an excerpt from their website:

2020 Edition

This edition includes more than 600 titles chosen by the Children’s Book Committee as the best of the best published in 2019. In choosing books for the annual list, reviewers consider literary quality and excellence of presentation as well as the potential emotional impact of the books on young readers. Other criteria include credibility of characterization and plot, authenticity of time and place, age suitability, positive treatment of ethnic and religious differences, and the absence of stereotypes. Each book accepted for the list is read and reviewed by at least two committee members and then discussed by the committee as a whole.
