In which section of the library would you find a compact disk of a speech?

You would typically find a compact disk of a speech in the media or audio-visual section of the library. This section often houses various formats of recordings, including CDs, DVDs, and audiobooks. If the library has a designated area for reference materials or archives, you might also check there for historical speeches. If you're unsure, asking a librarian for assistance can help you locate it more quickly.
