“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. And the City Council will most likely have to draw from a smaller pool of funds to help make up the difference than it has in the past.”
