Alternatively, I would drive to Dannemora in Clinton County where Northern New York American-Canadian Genealogical Society moved their library last year. That's 4 hours 50 minute and 315 miles. It is open from 9 to 3 on Saturday. I have not been to NNYACGS in a long time and would love to see the new library in the new location.
The third choice is the path of least resistance using less gas guzzling mileage, less transportation time and less money using MetroNorth trains and a few block to the New York Public Library at Bryant Park. That was the choice I took yesterday when I wanted to use Dictionnaire Genealogique Familles Acadienne, the definitive work documenting Acadian ancestors by Stephen White. I emailed the library three days ahead to be certain the books would be available and got a conformation. Saturday morning , I took the train to Grand Central and walked two blocks to Fifth Avenue and Library Way.
