The appropriate "Ask a Librarian" box is required on the home page for the each guide. Reusable boxes are available for each Ask a Librarian form available at the Library of Congress. There is a general Ask a Librarian box for use in any guide, if a more specific one is not appropriate.
Display your reading room/division's relevant "Ask a Librarian" on each research guide home page. Reuse "Ask a Librarian" boxes from: https://guides.loc.gov/reusable-boxes
