See Z. Haraszti, The Enigma of the Bay Psalm Book (1956).
The book is a Psalter, first printed in 1640 in Cambridge, Massachusetts. The Psalms in it are metrical translations into English. The translations are not particularly polished or poetic, and none have remained in use, although some of the tunes to which they were sung have survived (for instance, "Old 100th.") However its production, a mere 20 years after the Pilgrim Fathers arrived at Plymouth, Massachusetts, represents a considerable achievement. It went through several editions and remained in use for well over a century.
The early residents of the Massachusetts Bay Colony brought with them several books of psalms: the Ainsworth Psalter (1612), compiled by Henry Ainsworth for use by Puritan "separatists" in Holland; the Ravenscroft Psalter (1621); and the Sternhold and Hopkins Psalter (1562, of which there were several editions). Evidently they were dissatisfied with the translations from Hebrew in these several psalters, and wished for some that were closer to the original. They hired "thirty pious and learned Ministers", including Richard Mather and John Eliot, to undertake a new translation, which they presented here. The tunes to be sung to the new translations were the familiar ones from their existing psalters.
The first edition of the Bay Psalm Book to include music was the ninth edition, of 1698, which included tunes from John Playford's A Breefe Introduction to the Skill of Musick (London, 1654).
The title page of the first edition of 1640 reads:
Cambridge, Mass. Stephen Day
Imprinted, 1640
Eleven copies of the first edition of the Bay Psalm Book are known still to exist. One of them is in the Library of Congress, one is owned by Yale University, one by Brown University, one by the American Antiquarian Society, one by the Rosenbach Museum & Library and two, housed in the Rare Book Collection at the Boston Public Library, are owned by Old South Church in Boston.
The discovery of a twelfth complete copy was one of the plot points in David Baldacci's 2006 thriller novel, The Collectors
