‘Whose reviews’ influence libraries’ purchasing decisions?

When library staff utilize reviews to determine books’ suitability, “whose voices are privileged and whose go unheard” among the reviews that they read? At Reading While White, Megan Schliesman addresses concern about library collection-development policies that emphasize “professional” reviews. Schliesman argues that professional review journals lean toward “traditional” publishing, which in turn has a bias toward “whiteness” in children’s and young adult literature. She highlights sources of critical discourse beyond the traditional outlets, which can help to foster the diversity of viewpoints that a library will ideally strive for.
