The Connecticut Digital Archive (CTDA) is an example of the valuable online resources libraries can provide, describing itself as "a digital repository program and community dedicated to the preservation, maintenance, and delivery of a wide range of digital cultural heritage resources from memory institutions in Connecticut." This large archive includes dozens of collections with more than 75,000 digital items from public libraries, museums, and educational institutions throughout the entire state. First-time visitors may want to start by exploring the featured collections listed on the home page, which currently include the P.T. Barnum Digital Collection, the Connecticut State Museum of Natural History, and Newspapers of Connecticut, among others. Readers may search within specific collections or across the entire archive by keyword, topic, genre, place, or other fields via the site's advanced search option. Launched in November 2013, the CTDA is a collaborative program between the University of Connecticut Library and the Connecticut State Library, and it is also a partner of the Digital Public Library of America.
