Baird's Manual of Fraternities and Sororities

[oldu]

Why is it so much more difficult to get chapter information from NPHC organizations? Most of the groups simply don't list it. In doing some research on a specific campus I found several cases where a chapter name has been re-given. Is this a common practice? I can see how difficult the project would be; however, if a request from a respectable organization about to publish an updated Baird's surely each group would want to be as accurate as possible.
