Is anyone on this list familiar with a 4 volume set of books entitled The
Documentary History of the State
of New York by E.B. O'Callaghan published by Weed, Parsons & Co. , Albany,
1850?  It appears to be
a compilation of primary source material beginning (I believe) in the
1600's.  If you know of the books,
do you know if this is mostly information that can be elsewhere obtained (in
more recent publications).
My main question is, is it a worthwhile purchase?
