Ranging from Victorian picture stories to Disney classics and contemporary works on environmental issues, pop-up and movable books have amused, enlightened, and entertained children and adults for almost 150 years. Although most movable books are designed primarily for children, a significant number of fiction and nonfiction titles are intended for adult readers. Despite their enormous popularity, they are rarely reviewed or included in lists of children's books, and are seldom purchased for circulating libraries. Many are unindexed. Montanaro identifies, indexes, and describes over 1,600 titles by publication date, personal names of contributors, and series titles.
