JSTOR is a full-text database of scholarly journals and ebooks.  Journal content typically starts with the earliest volume but does not include the most recent 3-5 years.  JSTOR also includes the entire database of rights-cleared images formerly found in Artstor, as well as images and primary source collections contributed by member organizations.

Off campus users: To avoid CAPTCHA errors during peak times, use VPN for access.  Google Scholar allows you to simultaneously search scholarly content across many disciplines, databases, and information sources. Results can include books, articles, chapters, conference proceedings, and more.
