A Note to Researchers

To conserve space, I have confined most of the citations to books rather than to articles. For book citations, I have given the original date of publication, in order to highlight the continuity and historical development of the ideas involved. In many cases, this helps one grasp their wider meaning. For those interested in locating the most recent edition of any particular work, Amazon.com is the fastest source.

For those interested in locating the publisher and place of a book listed, any online state university library can readily provide that information, such as California's www.melvyl.ucop.edu or Ohio's www.ohiolink.edu. The latter also provides OCLC numbers (online computer library center) for ordering interlibrary loans. Many of the standard works on learning psychology are listed at http://psychclassics.yorku.ca.
