Masters degree in Library and Information Science is effectively the professional degree for librarians in the Americas.

The Information in ``Library and Information Science'' is used in the pre-Shannon/pre-information theory sense to meaning `knowledge.' LIS degrees are indeed strongly rooted on the humanities side of C. P. Snow's ``Two Cultures'' (C. P. Snow's 1959 book was the the first widely circulated and clearly defined drawing of a line between the sciences and the humanities in terms of academic culture, perception of purpose and motivation). Librarians, as maintainers of the physical manifestation of the the Literary Canon, are arguably as deeply part of the humanities as the classicists.
