A member country checklist is available on the website.
Proofs sent by post: The countries list is provided on the reverse side of the page(s) containing your printed proof description. We welcome additions / corrections on that side of the page.
Proofs sent by e-mail: Please refer to the checklist on our website. You are welcome to send us membership country details in whatever way suits you as long as the changes / additions are clear for the editors. Thus you may make changes to the proof text paragraph describing countries of membership or you may send the countries list as a part of your reply.
