General Copyright Information and Permissions

AAPG Owns Copyright on Most of its Publications

AAPG obtains copyright of both print and digital/electronic ownership from most authors of articles and books published by AAPG. If any material requested was reprinted by AAPG with the permission of another publisher, it is the responsibility of those requesting permission to obtain permission from that original publisher.

Open Access

AAPG allows authors to elect Open Access publishing as part of compliance with certain governmental funding initiatives. In such instances use of this material may be covered by a Creative Commons License. Review AAPG’s Open Access Policy

AAPG Authors

Authors wishing to use AAPG copyrighted material within work being published by AAPG are not subject to fees nor do they need to seek permission from AAPG; however, it is the responsibility of authors to provide proper citation. Permission without a fee is granted to AAPG authors who wish to republish portions of their own work as long as AAPG copyright credit is given. For both instances please refer below to “Condition of Grant of Permission”.

Special Fair Use Permission

If you want to use a single figure, a brief paragraph, or a single table from an AAPG publication in a paper in another publication, AAPG considers this to be fair usage, and you need no formal permission. In that case, you should print a copy of this document and present it to your publisher. You are, however, required to provide proper citation.
