Books published by Houghton Library of the Harvard College Library

Walsh's pioneering catalogue of the Harvard collection of 15th-century printed books was published in five volumes. The First Supplement describes 202 new incunabula at Harvard: 67 complete or nearly complete copies and 135 single leaves or fragments, representing a total of 173 editions, including 110 not in Walsh's original five volumes.

In 1987 the Houghton Library observed the 150th anniversary of Pushkin's death with an exhibition of materials from the extraordinary Russian literature collection assembled by Bayard Kilgour. From this trove, curator Malmstad chose books, letters, and manuscripts that illuminated Pushkin's life, career, and the world of his influences and rivals.

The generously illustrated essays in this collection of proceedings from a 2007 conference explore three medieval manuscripts of Ambrosian chant owned by Houghton Library as physical objects, and place them in their urban and historical contexts, as well as in the musical and ecclesiastical context of Milan, Italy, and medieval Europe.
