NPG's post-cancellation policy ensures institutional customers can retain access to all licensed material upon cancellation of the license agreement. It is applicable to all institutional customers with a license agreement signed in 2006 or thereafter. Access is subject to payment of an annual access fee.

The access fee supports the costs of hosting content and related customer service. It is payable per publication. Access fees do not apply to customers with a current license to the relevant publication.

NPG's post-cancellation policy applies as far as possible to all journals published by NPG. Post-cancellation rights do not apply to those journals that offer open archives after 12 months, and some journals owned by scholarly societies may adopt different policies. Any exceptions to the policy are indicated on the license agreement.
