Between 1650 and the year of Field's death (1668) there was, as may be seen from Appendix II, a considerable output of books from the press. Not many are of intrinsic importance, but the titles show considerable variety and a further point of interest is that the printer's copies of a large number of _imprimaturs_ of books printed between 1656 and 1692 have been preserved[64]. Orders "for the better government of the presses and Printers" were reaffirmed by the Vice-Chancellor and Heads in 1655 and it is clear that the university at this time exercised a closer supervision over its press than in the days when Buck conducted his independent negotiations with the London Stationers. The specimen _imprimatur_ which is reproduced overleaf shows the care with which Field preserved his authority for printing any particular book. One of the first books printed by Field was _The History of the University of Cambridge_ by Thomas Fuller (1655), who, in spite of his Royalist convictions, appears to have raised no objection to his work being printed by one who styled himself "one of his Highness's Printers." [Illustration: _IMPRIMATUR_ FOR A BIBLE, 1662] Cromwell's death in 1658 called forth the customary _Musarum Cantabrigiensium Luctus & Gratulatio_, containing a Hebrew poem by Cudworth; whilst two years later Field, with fine impartiality, printed _Academiae Cantabrigiensis ΣΩΣΤΡΑ_, as well as two editions of the speech delivered by Richard Love in honour of the return of Charles II and a sermon by John Spencer on the same happy theme. Several bibles were printed during this period, including a folio "with Chorograph Sculps by T. Ogilby" (1660)[65]. Field, however, did not (in the earlier years of his career, at any rate) maintain the high reputation of Cambridge bibles established by Buck and Daniel; for in 1656 William Kilburne presented a statement to the Vice-Chancellor showing a long list of errata in bibles printed by Field in 1653, 1655, and 1656. These errata were based upon an examination only of a few sheets and in a note at the end of the list it is stated: If those severall Bibles were read over throughout, they would be found egregiously erroneous, without all question; And of the severall Impressions, there were about fower score Thousand printed, And all, or the greatest part of them sold by Mr Field and dispersed, to the great scandall of the Church[66]. Amongst the editions of classical authors printed during this period may be noted Statius (1651), Poetae Minores Graeci (1652, 1661, 1667), Terence (1654), Cicero, _de Officiis_ etc. (1660), Homer (1664), Sophocles (1665, 1669), Sallust (1665). Editions of Euclid appeared in 1655 and 1665, the former by Isaac Barrow, afterwards Lucasian Professor and Master of Trinity College.
