I just heard about these forthcoming four volumes on early women’s works: 900-1550, 1550-1603, 1603-1625 and 1625-1650. Not all will be of use to philosophers, but it looks like a resource worth having if one is at all interested in women’s writings of these periods. The webpage includes links to extracts and table of contents.
Seems definitely worth ordering them for one’s university library.
