Catalogus Librorum Manuscriptorum in Bibliotheca D. Thomæ Phillipps, Bart., A.D. 1837 (Impressus Typis Medio-Montanis, 1837[–1871]).
I have a copy of the Orskey-Johnson reprint (2001) of the Phillipps catalogue. In the introduction A.N.L. Munby states that he knows of only about fifteen complete, or substantially complete, copies of the catalogue, of which only seven are available for consultation in public institutions, at the BL, London; Bodleian, Oxford; UL, Cambridge; BnF, Paris; KB, The Hague; Harvard, Cambridge (MA); and Newberry, Chicago. The reprint is a copy of one formerly owned by David Lew Feldman, New York.
[Any reader who does not know what an extraordinary book the Phillipps catalogue is, should consult the first volume of Munby's
Phillipps Studies (1951), or
this very brief summary]
In connection with an enquiry from a reader a couple of days ago I tried Googling a phrase from the catalogue, hoping that it might lead me to the present whereabouts of one of the manuscripts, but it took me instead to an
online copy of the catalogue itself, of which I was unaware.
