We are grateful to Betty Friedrich for scanning images, to Kristin Logan for key help in assembling the first web structure, to Lara Eakins for help with the Starry Night program and working out the nature of the Borana calendar stars in 300 BC and for her handiwork with Photoshop and to Mark Cornell for help in organizing files and security matters.

Special thanks go to Clara Fowler for introducing us to the UT information structure and to Molly White for help acquiring documents and copywrite issues.

We especially grateful to Larry Robbins whose mail unlocked for us the subsequent survey missions to Namoratunga II, to Keith Snedegar for his encouragement, and to Kim Malville and Fred Wendorf for permission to use images of their work on Nabta and for fruitful references.
