The 'Journal of the Experimental Analysis of Behavior' at Fifty

The "Journal of the Experimental Analysis of Behavior" was founded in 1958 by a group of male psychologists, mainly from the northeastern USA and connected with either Harvard or Columbia. Fifty years later about 20% of both editors and authors reside outside this country and almost the same proportion is women. Other changes in the journal include having its own website for more than a decade and now publishing online as well as on paper. A recent connection with PubMed Central of the National Library of Medicine has made possible the completely free electronic presentation of the entire archive of about 3,800 articles. (Contains 5 tables and 3 figures.)
