Regulation 25 Reader access to relevant material
A copyright owner or database right owner in relation to relevant material may make a request in writing to a deposit library to withhold access to that relevant material from readers for a specified period of time.
The deposit library receiving the request must comply with that request if the following conditions are met —
the period specified in the request does not exceed three years from the date on which the request is made;
the deposit library is satisfied on reasonable grounds that, for the period specified in the request, viewing of the relevant material by a reader would, or would be likely to, unreasonably prejudice the interests of the person making the request.
The entitlement to make a request under paragraph (1) includes an entitlement to make subsequent requests, and (subject to paragraph (4)) a deposit library must comply with a subsequent request if the conditions in paragraph (2) are met in relation to that request.
If a subsequent request seeks to extend the specified period of time relating to an earlier request made under paragraph (1), that subsequent request must be made at least one month before the specified period expires.
