The Library is a place of lifelong learning

The Andrew Carnegie Free Library & Music Hall (ACFL&MH) has served its community since 1901. The Library was built by Andrew Carnegie as a gift to the community. The Andrew Carnegie Free Library & Music Hall is one of only four endowed libraries built by the philanthropist in the United States. (The others are in Braddock, Homestead and the sadly demolished Duquesne Carnegie Library.)

In 1894, the two boroughs of Mansfield and Chartiers consolidated to become Carnegie. The Library & Music Hall is Andrew Carnegie’s enduring thank you gift to the community that took his name. Furthermore, the Andrew Carnegie Free Library & Music Hall is the only library in the country bearing Mr. Carnegie’s first name.

A Word about Book Donations

People who love books hate to throw them away and often bring them to the library as a donation. While we accept donations, we reserve the right to choose whether we add them to our collection, sell them, or recycle them. The library accepts donations with the understanding that they will be added to the collection only if appropriate and needed. If they are not needed because of duplication, condition, or outdated information, the donor gives approval to dispose of them. Gifts must meet the same standards as other materials selected for inclusion in the library’s collection. The Andrew Carnegie Free Library encourages and appreciates donations as long as they are clean, free of mold, musty or cigarette smoke smells, water and/or bug damage, markings, stickers and other visible defects. Covers must be attached. All pages must be present. We do not accept encyclopedias, Reader’s Digest condensed books, magazines or VHS tapes.

By law, the library is not allowed to appraise the value of donated materials, though it can provide an acknowledgment of receipt of the items if requested by the donor.
