Criticism or review - allows the use of short extracts or quotations for the purposes of critique and review. Use must be genuinely for this purpose and not for illustrative or enhancement purposes.
Quotation - allows the use of quotations for purposes other than criticism and review. The length of a quote should not be more than is needed for the specific purpose of use.
Both permit the use of limited extracts of any type of copyright work provided the work has been made available to the public e.g. published. The amount you can use is subject to a fair dealing test and you must acknowledge the source.
