This presentation will discuss two current crowdsourcing activities that the Biodiversity Heritage Library (BHL) has initiated.  The first is through the Zooniverse platform in which users are asked to classify and describe natural history illustrations from 19^th century periodicals found within the BHL.  The second is through two online games, called Beanstalk and Smorball, which BHL commissioned from Tiltfactor (http://www.tiltfactor.org/), based at Dartmouth College.  In the games, users help with OCR text correction by typing in words displayed on the screen, which when correctly submitted, will either cause a beanstalk to grow or defeat players on an opposing team.  The authors will discuss how each interface was developed around the particular goals of the tasks and the advantages and disadvantages of those environments.  Extraction of the information from the external platforms and integration into the BHL platform will also be discussed.
