Sufficient acknowledgement meaning

In practice, a sufficient acknowledgement is the credit that must accompany use of a copyright work when relying on particular fair dealing exceptions. It means identifying the work and the author in a way appropriate to the medium and context, so that a reasonable reader, viewer or listener can see what has been used and by whom it was created. The term is defined in legislation in the UK (Copyright, Designs and Patents Act 1988) and Ireland (Copyright and Related Rights Act 2000). It is typically required for fair dealing with a work for criticism or review, quotation, reporting current events, and illustration for instruction, and in some library and archive uses. Some UK provisions excuse acknowledgement where it is impossible for reasons of practicality; Irish provisions are broadly similar in effect. Usage is consistent across England & Wales, Scotland and Northern Ireland. What is “sufficient” is fact‑specific. As a practical rule: name the author (if known or reasonably ascertainable) and identify the work by title or clear description, and give the credit near the use and with reasonable prominence. Failure to provide sufficient acknowledgement may defeat the relevant exception and expose the user to copyright infringement.
