Which entity manages PRONOM?

The correct answer is that the entity that manages PRONOM is the National Archives (UK). PRONOM is a digital preservation tool and an online registry that provides information about file formats, their characteristics, and the tools that support their preservation. Managed by the National Archives in the UK, PRONOM plays a crucial role in assisting institutions and individuals in understanding how to preserve digital information effectively over time.

The National Archives actively maintains PRONOM to ensure that it remains updated with the latest developments in digital formats and preservation technologies. This is essential for ensuring long-term access to digital materials, making PRONOM an invaluable resource in the field of digital archiving and preservation.

The other entities mentioned have important roles in the context of libraries and archives, but they do not manage PRONOM. The Library of Congress, for example, is a leading institution in the United States concerning library and archival practices, while the British Library focuses on preserving the national collection of published and unpublished items. The Smithsonian Institution is known for its museums and research, but none of these organizations have the responsibility for maintaining PRONOM.
