borrowed

In a library, high demand refers to materials that are in high demand or are being used frequently by patrons. These materials may include popular books, movies, music, or other items that are borrowed often or have a long waitlist. Libraries may keep a high-demand collection to ensure that these materials are readily available to patrons. High-demand materials may be placed on hold or reserved for patrons, and they may have shorter loan periods or be subject to additional fees to encourage their timely return.
