An offprint is a separate and distinct print of a publication, typically an article or chapter, that is produced in addition to the original edition. It is often used for promotional or archival purposes, and may contain additional or updated information not found in the original. Offprints are commonly distributed to authors, researchers, and other interested parties as a means of sharing and disseminating knowledge. They serve as a tangible representation of the intellectual contributions made by individuals and are often prized possessions in academic and professional circles.
