Thanks to Anna Wigtil, a librarian at UNL, there are two guides to use as inspiration for suggested reading.
Anna created a LibGuide showcasing Nebraska poets, including poetry books from Nebraska 150 as well as Nebraska Book Award winners. Check it out here: http://unl.libguides.com/nebraskapoets
She also created a Goodreads list of the Nebraska 150 books: https://www.goodreads.com/list/show/109960.Nebraska_150_Books
