The most common implementation of representation sharing in functional programming systems is known as hash-consing. In the context of Prolog, representation sharing has been given little attention. Some current techniques that deal with representation sharing are reviewed. The new contributions are: (1) an easy implementation of {\\em input sharing} for {\\em findall/3}; (2) a description of a {\\em sharer} module that introduces representation sharing at runtime.
