Manuscript libraries are collections that house handwritten documents, often referred to as manuscripts. These libraries preserve a variety of texts, including historical documents, literary works, and religious texts. They play a crucial role in the study of history, literature, and culture by providing access to original materials that offer insights into past societies. Many manuscript libraries also focus on conservation and digitization efforts to protect fragile documents and make them accessible to a wider audience. Notable examples include the British Library and the Vatican Library, which contain invaluable manuscripts that are essential for research and education in various fields.
