From March 2003, an article in the Times Herald-Record:

Local artist Phillip Rudolph is taking on quite an ambitious endeavor in renovating the long-vacant Liberty Street School.

He wants to turn this forgotten school, sold by the school district in the 1980s, into an art center where the community can take classes and display work. Rudolph has organized a group of civic-minded folks to help.

Prognosis: It's on its way. The City Council agreed to enter into a land disposition agreement with Rudolph and the paperwork should be finalized shortly, said City Manager William Ketcham.

There's one large challenge: money. The group must raise cash to fix a leaky roof that has nearly demolished the interior.

It would seem the cash did not get raised.

The Liberty Street School is building 22. on this map. Here's an excerpt:

The Village of Ellenville was able to get another of Frank E. Estabrook's buildings listed in the National Register of Historical Places.

According to a short article in the New York Times archive, in April 1922, "Members of the Board of Education of Newburgh have barred, by a vote of 6 to 2, married women whose husbands are working from further employment in the schools of the city."
