Though plants have enormous value for society in terms of food, medicine, the environment, and economics, and hold significant social and cultural value, no single site provides accurate, comprehensive, and open access data on the known species of flowering plants.  This grant to the New York Botanical Garden (NYBG) supports its efforts become one of four lead international institutions spearheading the creation of World Flora Online (WFO), the first open access, online resource for accurate and comprehensive information for all of Earth's 350,000 known plant species.  NYBG will also become one of a dozen major content hubs for the Digital Public Library of America (DPLA), making available not only its first 20,000 plant species records and all 85,000 records when completed, but also depositing over a million existing plant specimen records in DPLA's index, a 15 percent increase in DPLA's current holdings.
