Father Garnet's works were written in England during the last decade of the sixteenth century when the persecution of priests was at its most intense and Catholic literature was systematically suppressed. They were written anonymously and those that were printed were printed secretly, without indication of place or date. The result has been that his bibliography has remained in a state of confusion to this day. The earliest printed list of his writings, in Alegambe’s Bibliotheca Scriptorum Societatis Iesu (1643), is inaccurate and incomplete, and little attempt has since been made to supplement it. Southwell’s revised edition of Alegambe (1676) reproduces the original list without alteration. Dodd, in The Church History of England (1737–42), also follows Alegambe. The first and only attempt to check Alegambe’s list in the light of original documents is to be found in Oliver’s Collections…S.J. (1845) which gives some corrections and fresh information based on the Stonyhurst MSS. Gillow combines the findings of Dodd and Oliver, adding some speculations of his own which do not stand the test of investigation. Sommervogel and D.N.B. follow Gillow. The extent to which bibliographers blindly copy one another is not always fully realized. Before any satisfactory study of Father Garnet’s life and work can be begun it is essential that his bibliography should be re-established, if possible, from documentary evidence.
