Copy (duplicate, reproduction, and written material)

Types and characteristics

Copies differ by method, fidelity and purpose. Physical processes (printing, hand-copying, photographic reproduction) and chemical processes (printmaking, lithography) produce tangible duplicates. Digital copying creates bit-accurate replicas of files. Other common forms include facsimiles, drafts, proofs, masters and editions. The fidelity of a copy depends on technique, materials and the intended use.

History

Human copying predates modern technology: oral repetition and hand-copying by scribes transmitted texts for centuries. The invention of movable type and the printing press made mass reproduction practical; later inventions such as lithography, photography, xerography and digital storage increased speed and uniformity. Each advancement changed how cultures define originals, editions and authenticity.

Written copy and copywriting

In publishing and marketing, "copy" refers to written material produced for readers: news articles, book manuscripts, web text, or advertising copy designed to inform or persuade. Copywriting is a professional craft combining clarity, audience awareness and persuasive technique to achieve communication goals.

Legal and ethical context

Copying raises legal and ethical issues. Copyright law protects original works and restricts unauthorized reproduction; exceptions such as fair use, fair dealing or licensed reproduction permit some copying. Questions of attribution, moral rights and provenance affect cultural and scholarly reuse. In computing, copying interacts with digital rights management, licenses and data integrity concerns.

Practical considerations

• Preservation: archival copies and digitization prioritize fidelity, metadata and long-term access.
• Publishing: editing, proofreading and typesetting produce successive copies (drafts, proofs, final versions).
• Legal use: certified or notarized copies and chain of custody matter for records and evidence.
• Computing: backups, checksums and version control help manage copies and protect authenticity.

Distinctions and value

A copy is distinct from an original by provenance, context or unique marks; early impressions, artist proofs or autographed items may carry special value despite being visually similar. Understanding the kind of copy and its intended function helps determine quality, rights and permissible use.
