Volumes compiled by Barry Flanagan and his assistants, partially in collaboration with Rowan Gallery, London, UK and Waddington Galleries, London, UK as a record of work. Some of the early volumes were maintained in duplicate by Barry Flanagan and Waddington Galleries. They were amalgamated into a single series and then, in the late 1980s, partially reorganised. Some earlier records were integrated into larger volumes arranged by medium.
