Archives are collections of documents, records, and other materials that are preserved for their historical, legal, or informational value. They can include a variety of formats, such as paper documents, photographs, audio recordings, and digital files. Archives are often maintained by institutions like libraries, museums, or government agencies to ensure that important information is accessible for research and reference. The purpose of archives is to safeguard the past and provide a resource for future generations. They help researchers, historians, and the public understand historical events, cultural heritage, and societal changes. Notable examples of archives include the National Archives in the United States and the British Library in the United Kingdom.
