The Library holds, acquires, preserves, and provides access to both historic and current books and journals, as well as archival materials, on a wide variety of disciplines that fall under the following subjects: natural history, botany, pharmacy, medicine, scientific history, and visual arts. The collection contains materials related to the discovery of new medicinal agents in plants, the history and the uses of natural products, the history and development of pharmacy and pharmaceuticals, b current herbal medicine and alternative therapies. There are over 200,000 volumes in the collection. There are nearly 1000 linear feet of archival and special collections materials, which provide information on the historic aspects of the Lloyds, their pharmacy, and pharmaceutical development. These primary resources enhance our understanding of current pharmaceutical practice, methods, drug development, and medicinal botany.
