Nearly a quarter of a century after her death, Mississippi writer Eudora Welty remains as relevant as ever, as a new documentary and related book project make clear. Welty, who died at 92 in her native Jackson in 2001, has already been in the news in our part of the world. “The Optimist’s Daughter,” a Welty novel set partly in New Orleans, was the Louisiana Book Festival’s One Book One Festival title this year. It’s also the latest selection for the Louisiana Inspired Book Club, which will feature a virtual discussion of the book at 12:15 p.m. on Dec. 10. Readers can find more info at www.nola.com/book_club.
