Conditions of use

Applications of this package (including the copying of text and images) are encouraged, without fee, provided copies are not made or distributed for direct commercial advantage and the source is acknowledged in publications of all kinds. We would appreciate being informed of such applications.


We would appreciate constructive comments, and will try to correct errors as they are pointed out. In particular, we would be interested to hear from suitably knowledgeable persons interested in collaborating as joint authors in further development of the package. In addition to improving the present descriptions, this could include extending the geographical coverage, and preparing parallel accounts for other regions. Alternatively, the DELTA data and associated files could be donated to any person or institution interested in developing them further.
