It will be noted that in the course of the 19^th century no less than thirty-six different hymn-books appeared, a far larger number than any other American denomination can show for the same period, and illustrative of the extreme individualism of the Unitarian churches. Throughout the middle third of the century Greenwood’s _Collection_ (13), the _Springfield Collection_ (14), and the _Cheshire Collection_ (20), had the widest use, followed in the last third of the century by the _Hymn and Tune Books_ (34) and (36) of the American Unitarian Association, but all the other collections had some local vogue, in some cases only for a brief period or only in those churches the ministers of which had compiled the collections in question. As late, however, as the beginning of the 20^th century, at least eight different hymn-books were in use in the Unitarian churches of the United States and Canada. This diversity of usage declined rapidly after the publication of _The New Hymn and Tune Book_ (45) in 1914, and had practically disappeared by the time when that book’s successor, _Hymns of the Spirit_ (48) was published in 1937. BIBLIOGRAPHY Copies of at least one edition of each of the following books are in the Historical Library of the American Unitarian Association, 25 Beacon Street, Boston, except in the cases noted. 1. _A Collection of Hymns, more particularly designed for the Use of the West Society in Boston_—Boston, 1782; 2nd ed., 1803; 3rd ed., 1806; 4th ed., 1813. The editor is said to have been Rev. Simeon Howard (1733-1804), (See Bentley’s _Diary_, II, 371), Jonathan Mayhew’s successor as minister of the West Church. Mayhew’s congregation was notably liberal and this book represents the first step away from psalm-books of the traditional type. It contains 166 hymns, including a number of classics by Watts, Barbauld, Addison, etc. The tone in general is ethical rather than theological, and many of the hymns are moral precepts in mediocre verse, some, at least, probably of local production, but the authors cannot be identified as no author is named; there is no preface, and the compiler’s name is not given. Note:—The American Unitarian Association does not own a copy. There is one in the Congregational Library, 14 Beacon Street, Boston. 2. _A Collection of Hymns for Publick Worship_—Salem; n.d. (1788)
