A "permanent collection" refers to a group of artworks or artifacts that are owned by a museum or gallery and are intended to be displayed for an extended period. These items are typically not for sale and are often considered essential to the institution's identity. The collection can include various forms of art, such as paintings, sculptures, and historical objects. Museums like the Metropolitan Museum of Art or the British Museum curate their permanent collections to showcase significant pieces that reflect cultural heritage and artistic achievement. These collections are often supplemented by temporary exhibitions, but the permanent collection remains a core part of the institution's offerings.
