This may seem superfluous at first sight, but may possibly be no longer thought so, when I shall have acquainted my Reader, that when I was making my Collection, I found several Plays and Masks, bound up with other Poems, which by the name were scarce known to the generality of Booksellers: as for instance, Sir =Robert Howard='s =Blind Lady=; =Daniel's Philotas=; =Carew='s =Coelum Britanicum=; =Shirley='s =Triumph of Beauty;= with infinite others. But two Plays I might particularly mention, both taken notice of in former Catalogues, to wit, =Gripus and Hegio=, a Pastoral; and =Deorum Dona=, a Masque; both which were written by =Baron=, and were wholly unknown to all the Booksellers of whom I happened to enquire, and which I could never have found but by chance; they being printed in a Romance called, =The Cyprian Academy=, in 8o. The same I might add of =The Clouds=, (a Play which was never in any Catalogue before, and was translated from =Aristophanes='s =Nubes= by =Stanley=, and printed with his =History of Philosophy=, Fol. =Lond. 1655=, and now newly reprinted; and of several others) but that I must hasten back to give an Account of the two other Divisions of my Catalogue. The =one= of which contains those Plays whose Authors discover themselves but by halves, and =that= to their intimate Friends, by two Letters only in the =Title-Page=, or the bottom of their =Epistle=; and in the last Degree are plac'd all =Anonemous= Plays; and thus compleats the =Fifth= Part. The =Second= Part contains the Catalogue =Reprinted= in an exact =Alphabetical= manner, according to the forms of =Dictionaries=, the Authors Names being here left out as superfluous; and against each Play is a Figure to direct you to the Page where you may find it in the First Part. Thus much as to the Method and Alterations of this Catalogue: Now as to the Remarks, which are of =three= sorts; the =first= of use, and the other =two= conducing to Pleasure at least, if not to Profit likewise. The =First= is to prevent my Readers being impos'd on by crafty Booksellers, whose custom it is as frequently to vent =old= Plays with =new= Titles, as it has been the use of the Theatres to dupe the Town, by acting old Plays under new Names, as if newly writ, and never acted before; as, =The Counterfeit Bridegroom=, an old Play of =Middleton='s; =The Debauchee=, another of =Brome='s; =The Match in Newgate=, another of =Marston='s; with many more, too tedious to repeat. By these Remarks the Reader will find =The Fond Lady=, to be only the =Amorous Old Woman=, with a new Title, =The Eunuch=, to be =The Fatal Contract=, a Play printed above thirty years ago; with many the like.
