Our own Carol Robinson points out additional CFPs for the 2015 International Congress on Medieval Studies here. In addition to that of the Society, there are sessions hosted by the Medieval Electronic Multimedia Organization and the International Society for the Study of Medievalism. There is overlap among our organizations, certainly, but we are all dedicated to much the same goals and can work together easily and well.
Society members and others are encouraged to look over all three CFPs Carol brings up and to submit to any of them. The Society hopes to see a great many people at Kalamazoo in May 2015!
