Dagg to Professor Benjamin O. Pierce, letter excerpt, February 19, 1848:
"You inquire, what books our Library needs. I answer, All books of all sorts....We except only works of fiction, and light reading, and those of an immoral tendency. In Theology, we need a complete set of the ancient Fathers, and of the Reformers and indeed the distinguished Divines of every age. Our Library at present is so small, that there is very little risk of its being supplied with more copies of any work, than will be found useful."
