Herbert Grundmann 
Religious Movements in the Middle Ages [PDF ebook] 

Medievalists, historians, and women’s studies specialists will welcome this translation of Herbert Grundmann’s classic study of religious movements in the Middle Ages because it provides a much-needed history of medieval religious life–one that lies between the extremes of doctrinal classification and materialistic analysis–and because it represents the first major effort to underline the importance of women in the development of the language and practice of religion in the Middle Ages.
