In 2014, BHL welcomed the University of Illinois at Urbana-Champaign as a member. The University’s Library is a campus-wide network of libraries serving programs of learning and research in many disciplines and is the largest public university research library in the country with more than 13 million volumes. The Biology Library collection alone contains over 137,000 volumes. To date, the University Library has contributed over 1.2 million pages from over 4,400 volumes to BHL. Illustrations from many of these books have also been made available in the BHL Flickr.
