Landshuth, L[eser]. Amudei ha-Avodah

Biographies of the authors of religious poetry and bibliographies of their hymns found in the prayer books according to the rites of Poland, Germany, Spain, Rome, Carpentras and Algeria, both in print and manuscript. "One can say in general that Ammude Ha-Avoda bears witness to the understanding and clarity of mind of its compiler and even today is not without value for specialists in this area. Indeed, the punctilious citation of sources alone deserves special praise" (H.J. Schirmann, Introduction to Israel Davidson, Thesaurus of Medieval Hebrew Poetry, p. xviii)
