Supplementary content isn't available in Libby
Some titles you borrow in Libby come with supplementary material, which may be referenced in the title itself or on its details screen. Supplementary content can be a PDF, map, handout, or reference sheet.
Right now, supplementary content can't be accessed in Libby, but you can download it from your library's OverDrive website. Visit this OverDrive Help article to learn how.
