The American Library Association has a rundown of libraries affected by Hurricane Irene. Amongst the libraries is the Wells Memorial Library in Upper Jay, NY, which lost nearly its entire children's collection, including every single picture book.
Author Kate Messner has information about how you can help rebuild the library's collection (through monetary or book donations - see details in her post) and/or help with an upcoming silent auction fundraiser (they're looking for donations of original children's book art and also signed copies of children's books).
Please help if you can. Thank you!
