The Library of Congress Classification (LCC) is a classification system that was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress. Proposals for additions and changes are reviewed regularly at staff meetings in the Policy, Training, and Cooperative Programs Division (PTCP) and an approved list is published.
