And although I dare not be absolute in my Opinion, who is the best of this Age, yet I should be very disingenuous if I should not conclude that the _English_ Stage is much improved and adorned with the several Writings of several persons of Honour; but, in my Opinion chiefly with those of the most accomplished Mr. _John Dryden_.[16] For _Momus_ Langbaine did adopt many opinions and much information from the earlier catalogues. In the seven years between his first and second catalogues, however, he began to deal more carefully with bibliographical matters, especially in his attributions to Dryden, and he found a new format which would allow him to present his later catalogues in a more accurate, useful and stimulating manner. * * * * * _Momus Triumphans_ was published in November, 1687 (although its titlepage is dated 1688), under two different imprints: the one reproduced here and another "Printed for N. C. and to be Sold by _Sam. Holford_, at the Crown in the _Pall-Mall_. 1688." In both issues there is a major press variant on page 7 under Dryden in which "[148] Maximin--T. 4o" is deleted and the note correctly rekeyed to "Tyrannick Love, or Royal Martyr" in the right-hand column. Where this variant occurs both title and note for "[149]Mistaken Husband--C. 4o" are moved from the top of the right-hand column to the bottom of the left-hand column. In addition to its Preface, _Momus_ is divided into four sections: (1) Authors arranged alphabetically according to surnames, together with their plays, including the genre and format of each (pp. 1-26); (2) "_Supposed_ AUTHOURS" listed by initials with their plays, genre and format (pp. 27-28); (3) "_Unknown_ AUTHOURS" with plays divided alphabetically into groups by first initial of their titles (pp. 29-32); and (4) an Index of plays arranged alphabetically [pp. 33-40]. The alphabetizing is not exact, but the careful and efficient organization by format (with its handy, easily usable cross index)[17] is one of Langbaine's chief contributions to modern catalogue making. Furthermore, the format established in _Momus_ not only supports the enormous expansion which Langbaine himself makes in the _Account_, but it (in tandem with his marked prejudices) encouraged the copious annotations of later commentators. In other words, Langbaine discovered the form which was not only most useful to his contemporaries, but one which was to make him, in Osborn's phrase, "the chief tool of compilers for more than two generations."[18]
