Leonard Marcus might just be the busiest man in the world of kid lit. In June, the children’s literature historian and scholar launched a critically acclaimed exhibition at the New York Public Library (which he curated) and had a book published that celebrates the life and work of Maurice Sendak (which he edited). Marcus shared with SLJ some of the details of his recent projects, insider knowledge of children’s literature history and icons, and his belief that picture books might be the solution to saving all physical books.
