 In 2022, the library in Vinton closed for a short period of time after employees quit for political reasons following complaints and allegations by patrons that included: the head librarian's "hiring and support for LGBTQ+ staff"; books by Jill Biden and Kamala Harris, and none about Donald Trump; "LGBTQ-themed book displays in the children’s section"; and male staff members "wearing dresses". One of the library's former directors said they had 173 books about Christian life, and seven books about "LGBT, gay or transgender" topics; another former director said some patrons "would check out the books and not return them", rather than file written complaints about the books.  Contact Vinton Public Library for its current status.
