TOFT's video of the 1972 tour of Company (call number NCOV 12), taped in Washington D.C., has already been reformatted to DVD. I work at the library and can verify this. But at any rate, definitely call ahead for an appointment. And for what it's worth, the staff is always supposed to inquire why researchers wish to view a particular title, and 99% of the time they do.
As for the NYPL joining the 20th century, well, reformatting thousands of videos costs money. I wish we had the resources to be fully up to speed on everything. Donations are accepted with gratitude.
