This is a list for books, stories and poems that constrain vocabulary to a specific size, or use other vocabulary rules, often for the production of graded readers. While there is already a list for lipograms (https://www.goodreads.com/list/show/3...) such as Gadsby, which also can go here, this is for such books as Green Eggs and Ham and Up Goer Five where vocabulary is constrained. Can include any language, eg. , the "shi" Chinese poem.
