circulation

Print circulation is the average number of copies of a publication. The number of copies of a non-periodical publication (such as a book) are usually called print run. Circulation is not always the same as copies sold, often called paid circulation, since some issues are distributed without cost to the reader. Readership figures are usually higher than circulation figures because of the assumption that a typical copy is read by more than one person.
