Did someone ask about a study on Louise Farrenc? There is a fine book by
Bea Friedland, "Louise Farrenc, 1804-1875 - Composer, Performer, Scholar"
published by UMI Research Press.  (University Microfilms International,
Ann Arbor, Michigan)

My copy shows copyright date of 1975 (with revisions in 1980).
