Geologic Ethics & Professional Practices is now available on CD
This CD is a collection of articles, columns, letters to the editor, and other material addressing professional eth- ics and general issues of professional geologic practice that were printed in The Professional Geologist. It includes an electronic version of the now out-of- print Geologic Ethics and Professional Practices 1987-1997, AIPG Reprint Series #1. The intent of this CD is collection of this material in a single place so that the issues and questions raised by the material may be more conveniently studied. The intended ‘students’ of this CD include everyone interested in the topic, from the new stu- dent of geology to professors emeritus, working geologists, retired geologists, and those interested in the geologic profession.
AIPG members will be able to update
their copy of this CD by regularly down- loading the pe&p index.xls file from the
www.aipg.org under “Ethics” and by downloading the electronic version of The Professional Geologist from the members only area of the AIPG website. The cost of the CD is $25 for members, $35 for non-members, $15 for student members and $18 for non- member students, plus shipping and handling. To order go to
www.aipg.org.
