Missouri Secretary of State Denny Hoskins announced this week the suspension of funding to OverDrive, a distribution company that oversees popular e-book apps like Sora and Libby.

Libby is an app that allows users to check out thousands of library books digitally at no cost. All users need is a library card. Hoskins cited concerns that children could access inappropriate materials through these apps. A news release said he has contacted OverDrive for a review of its policies. "Our priority is protecting Missouri’s children while holding taxpayer-funded vendors accountable," Hoskins said in the release. "We expect OverDrive to clarify its policies and demonstrate how it is ensuring appropriate access to content." Hoskins said he is committed to "upholding standards that safeguard young readers while ensuring responsible use of public funds." The Missouri Library Association responded to Hoskins' decision, saying it disagrees with the move and believes the suspension was based on a misconception of how OverDrive works. The MLA clarified that school librarians select and categorize books through Sora, meaning that an elementary student cannot access books selected for middle and high school students. The MLA also said that it supports careful selection of books for students and that it encourages parents and guardians to talk with their children about book choices. "Access to a variety of materials increases children’s literacy, reading comprehension, understanding of the world, and overall student achievement," the MLA said in a news release. It emphasized that Sora is especially important for rural districts with less funding. "If there are concerns about any materials, MLA urges the Secretary of State to talk with librarians and the professionals curating these collections," the MLA said.
