DURHAM, N.H. — Some professors at the University of New Hampshire say they are appalled that the school’s librarians are throwing away thousands of books to make way for a new collection.

Dimond Library administrators say the books being tossed into a trash bin outside the library haven’t been checked out in 20 years.

UNH collection management librarian Jennifer Carroll says they would like to keep every book forever, but have to make room for new bio-science books and other collections.

WMUR-TV quotes art history professor Patricia Emison as saying the book dump is a travesty.

Emison says the books are needed to a show the history of particular studies.

UNH is discarding 36,000 volumes and storing another 15,000.

Librarians said they are working under a tight timetable.
