  ## Biography
  
  Josephine Adelaide Clark was born on 9 March 1856 to John and Caroline (Derby) Clark in Weston, Massachusetts. She graduated from Waltham High School in 1873, and continued to teach there after graduation. In the fall of 1876 she began attending Smith College and earned her Bachelor of Arts in 1880. After graduation, she taught until 1888 when she began attending Columbia College in New York City for library science.
  
  After graduation, Clark became the assistant librarian at the Gray Herbarium at Harvard University. She became the Botanical Bibliographer for the Division of Botany at the U.S. Department of Agriculture in 1891 and quickly became the Assistant Librarian for the whole department.
  
  While working at the U.S. Department of Agriculture, she first compiled the index currently known as the Gray Herbarium Card Index which was the first available to botanists in a card format and published at regular intervals. The index was first published in catalog format in 1891 and compiled in a card format in 1894. The card format enabled the botanist to order alphabetically, systematic groups or geographical groups. Clark was the main organizer of the index until 1903 when she turned it over to Mary Anna Day at the Gray Herbarium with 27,999 cards.
  
  From 1901 to 1907 she was head librarian for the U.S. Department of Agriculture before returning to Smith College as librarian, a position she held until 1919.
  
  She died of pneumonia on March 24, 1929, in Claremont, California. Her papers are held by Smith College.
