You will need to be a member of the Society and to log in below, to be able to use the facilities in the Members Area.
The Society publishes a detailed catalogue of World Petroleum Stamps. The 9th edition of Petroleum Stamps of the World is updated regularly, and is available here, for the use of members.
There is an additional subscription payable for this service. If you'd like to subscribe then please contact the membership secretary by using the contact form. You can
also very easily pay the fee online by PayPal, by completing the
membership application form
The additional subscription is US$25, but this payment is a one off, and will cover your catalogue subscription whilst you remain a PPSI member.
From the Members Area, members may also download copies of the latest edition of the Society journal, The Petro-Philatelist. In addition, all past editions are also now available for members to download.
