The NYTimes has reported that
Mayor Michael R. Bloomberg’s $63 billion budget for fiscal year 2011, which starts July 1, calls for a 31 percent reduction in financing for arts groups and a 25 percent cut for libraries — steeper than any such measures he has proposed at this stage of the budget cycle in the last eight years.

I haven’t come across the same thing on the arts budget side. If you find something, please let us know.
