Librarians unveiled the donation from the Grammy-winning country singer Thursday. Swift grew up in nearby Wyomissing and wasn't able to attend the event.
Swift partnered with publisher Scholastic Inc. to donate the books for children and young adults. The titles were chosen by local librarians.
Reading is a struggling city about 50 miles northwest of Philadelphia. Swift's representatives told library officials she wanted to help economically troubled libraries.
Librarians say Swift's books will be marked with a white star on the spine and a sticker inside. They say they hope Swift's popularity will motivate more children and teens to read.
