Anna Mae Howell, age 14, of Missoula, Mont., for her question:

HOW WERE CARNEGIE LIBRARIES BUILT?

Carnegie libraries are free public libraries built with money given by Andrew Carnegie, a Scottish American steel manufacturer. Carnegie donated the buildings on the condition that the communities in which they were located would supply and support the libraries.

During his lifetime, Carnegie gave more than $56 million to build more than 2,500 libraries in Canada, the United States and Great Britain, as well as in other English speaking countries.

There are about 1,700 Carnegie libraries in the U.S.

The last Carnegie grant for building a library was made in 1917. Since his death in 1919, the Carnegie Corporation of New York has given more than $13 million in grants to libraries.

Carnegie was born in Scotland in 1835 and came to America when he was 13 years old.
