The Gerritsen curators gathered more than 4,700 publications from continental Europe, the U.S., the United Kingdom, Canada, and New Zealand, dating from 1543-1945. The anti-feminist case is presented as well as the pro-feminist; many other titles present a purely objective record of the condition of women at a given time. The broad scope of Gerritsen Online allows scholars to trace the evolution of feminism within a single country, as well as the impact of one country's movement on those of the others. In many cases, it also provides easy access to primary sources otherwise available only in a few rare book rooms.
