What do you mean by the library?</h3>
A library is a collection of items, such as books or movies, that may be used instead of just being displayed. A library can be a real location, a virtual environment, or both that offer physical (hard copies) or digital access (soft copies) to materials. Printed materials and other tangible resources in a variety of formats, such as DVDs, CDs, and cassettes, as well as access to data, music, and other items stored in bibliographic databases, can all be found in a library's collection.
