Because of continually increasing publication costs, voluntary financial contributions to the AAPG Bulletin from its authors are of great assistance.

Inability to contribute will not prejudice the editorial processing or publication of an article.

If organizational funding is available, authors are urged to arrange $150 per page contribution to the AAPG Bulletin. The actual cost of printing one Bulletin page is approximately $400. Contributions are acknowledged on the Table of Contents page.

If you wish to make a tax-free contribution, the AAPG Foundation has established an endowment fund for the Bulletin. You can find more information at
