Contact Us


If you encounter a problem with ordering, or have any general questions or requests, please email us at and use “NDR Support Request” as the subject line. Please be specific as to what you need. Thanks.

We will try to respond within 48 hours. But please note, we are a small (two-person) firm, and we agreed with our print publisher DRI Press that for this Web edition we would keep overhead to a bare minimum, so that we could price the NDR far below most professional books of anything like its scope. And we both travel frequently.

We regret any resulting delay.
