It gives me great pleasure to acknowledge the very considerable help from fellow scholars and librarians that I have received in bringing this book into existence. I am indebted, as ever, to the Codrington Library of All Souls College, Oxford, and especially Gaye Morgan and Gabrielle Matthews, for their patient and tireless support over a long period of time. I am grateful to the Biblioteca d’Arte e di Storia di San Giorgio in Poggiale in Bologna for permission to transcribe in its entirety Gaspare Bindoni’s Catalogo de i libri della fiera di Franchfort passata di settembre MDCI. Di Gasparo Bindoni Libraro in Bologna : IT\ICCU\UBOE\077023, and to Daniele Olschki and Edoardo Barbieri for permission to reproduce the greater part of the following article: ‘Ciotti and Plantin: Italy, Antwerp and the Frankfurt Book Fair in Autumn 1587’, in Studi offerti a Dennis E. Rhodes per i suoi 90 anni, La Bibliofilia, 105 (2013), pp. 135–46. For permission to reproduce the signature of Andreas Frisius in MPM Archief 581 f. 5, I am grateful to the Museum Plantin-Moretus, Antwerp – UNESCO, World Heritage. Chapter 6 of this volume previously appeared as ‘The Thesauruses of Otto and Meerman as publishing enterprises: legal humanism in its last phase, 1725–1780’ and ‘Appendix: The Thesauruses of Otto and Meerman’, in Paul J. du Plessis and John W. Cairns (eds.), Ad fontes? Reassessing Legal Humanism and its claims (Edinburgh: Edinburgh University Press, 2016), pp. 299–346. The printer’s marks in Appendix 1 of Chapter 5 are reproduced by kind permission of the Warden and Fellows of All Souls College, Oxford and the Provost and Scholars of the Queen’s College, Oxford (in respect only of the mark used by Heinrich Wetstein in 1685–6 for the title-page of Francesco Redi’s Experimenta circa varias res naturales). Colleagues at All Souls College and elsewhere in Oxford have provided information, help and invaluable criticisms: Noel Malcolm, Dmitri Levitin, Robin Briggs, Boudewyn Sirks, Wolfgang Ernst, Will Poole, Philip Beeley, Giles Mandelbrote, and Cristina Dondi. The late Dennis Rhodes generously allowed me to consult his card catalogue of the publications of Giovanni Battista Ciotti before the publication of his monograph on this important publisher. I owe a very great debt to Angela Nuovo for her critical reading of draft chapters and her generosity in providing me with documents on early modern Italian book history of which she is the leading authority. Goran Proot, Andrea Ottone and Maria Alessandra Panzanelli Fratoni, Angela’s colleagues in the EMoBookTrade Project, have also been very helpful with documents, information and queries. David Lines of Warwick University provided me with access to a microfilm of the Aldrovandi papers. Dirk Imhof and Kristof Selleslach have given me privileged access to the Archives of the Plantin-Moretus
