Baird's manual help

[FuzzieAlum]

I just got my hands on a Baird's manual for the first time for a class paper, and somehow I anticipated it being more straightforward than it is. If there is anyone who is familiar with it and could help me out, I'd be super-appreciative.

1) In the college section, are all the chapters it lists under "NIC," "NPHC Men" etc. still open (as of printing), and are all the closed chapters listed under "Inactive"? If so, how is it possible for one group to be listed under Inactive, 1932-1962, but under NPHC Women's as opening in 1961? Does that mean two chapters at once for a very brief period?

2) I notice at one institution the same sorority is listed twice under active chapters, one starting in 1972 and one in 1974 (and it's not Kettering). Both chapters have a "(B)" after them. Alas, Baird's does not seem to have a key. What is the mysterious B?

I'm also surprised to see chapters listed without founding years in the college section ... but if you cross-check in the fraternity section the dates are there.
