Manuscript collections are groups of original documents, letters, diaries, or other written materials that are preserved for research and historical purposes. These collections can include works by notable individuals, such as authors, scientists, or political figures, and often provide valuable insights into their thoughts, experiences, and the time periods in which they lived. Libraries, archives, and museums typically house manuscript collections, making them accessible to scholars and the public. Researchers use these collections to study various subjects, including literature, history, and social sciences, as they offer firsthand accounts and unique perspectives that are not available in published works.
