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.
