3. Investigate using computerized periodical indexes if available in your library. Sociological Abstracts online covers most sociological writing since 1974. A recent search found more than 420 articles having to do with cohabitation. Some dealt with laws about cohabitation while other focused on trends in other countries. Expanded Academic Index covers general interest periodicals
(Time, ms., National Review, Atlantic Monthly, and so forth) for the most recent four years; it also indexes the New York Times for the last six months. These electronic systems may be connected to a printer, allowing you to produce your own printout complete with bibliographic information and sometimes even abstracts of articles.
