18 In Venice, it is estimated that a press could be bought for between fifteen and thirty ducats; fonts, depending on their quality, would cost between fifteen and a hundred ducats. See Marino Zorzi, “Stampatori tedeschi a Venezia,” in Venezia e la Germania. Arte, politica, commercio, due civiltà a confronto, ed. Gaetano Cozzi et al. (Milan: Electa, 1986), 115–33, here p. 123.

21 ASVe, Senato, Deliberazioni, Terra, reg. 14, image 224, October 17, 1502. Lowry, The World of Aldus Manutius, 100, considers this a reasonable estimate.

Pettas, “The Cost of Printing a Florentine Incunable,” La bibliofilía 75, no. 1 (1973): 67–85, here p. 69.

23 ASVe, Giudici di petizion, Sentenze a giustizia, b. 159, fols. 44–47, 1473: the printer stresses that his workers could not “live from spirit” alone and that he had to provide them with sufficient “bread, meat, and other food, with a part of their wages too” (unless otherwise stated, translations of Venetian sources are our own). See also Tullia Gasparrini Leporace, “Nuovi documenti sulla tipografia veneziana del Quattrocento,” in Studi bibliografici.

Even considering that the ducat in around 1500 was worth one and a half times the value of the Florentine florin in around 1400 (a very broad estimate), the printers’ costs were still much higher.

25 This phenomenon is noted in Edoardo Barbieri, “L’accueil de l’imprimé dans les bibliothèques religieuses italiennes du Quattrocento,” in Le livre voyageur. Constitution et dissémination des collections livresques dans l’Europe moderne (1450–1830), ed. Dominique Bougé-Grandon (Paris: Klincksieck, 2000), 53–91, here pp. 56–57.

27 For a review of work on these sources, see Angela Nuovo, Il commercio librario nell’Italia del Rinascimento (Milan: Franco Angeli, 2003), 25–31. There is, however, a bias in these sources: some works were probably being offered for sale for the second time, since the trade in new and second-hand books took place on the same stalls; see Nuovo, The Book Trade in the Italian Renaissance, 347. For a study of the catalogues of Aldus Manutius, see Catherine Kikuchi, La Venise des livres, 1469–1530 (Ceyzérieu: Champ Vallon, 2018), 143–44.

33 This was the refusal to renew Daniel Bomberg’s privilege for works in Hebrew. It was notified by the Council of Ten and reflected religious circumstances that were problematic for this kind of publication: ASVe, Consiglio dei Dieci, Deliberazioni, Comuni, reg. 1, fol. 76, October 12–16, 1525; filze, no. 3 and no. 7, December 7, 1525; Marin Sanudo, Diarii, ed. Rinaldo Fulin et al. (Venice: Visentini, 1831), 40:56 and 75; 41:56 and 118.

34 There could, however, be a bias in obtaining privileges. Petitioners of Italian origin were more likely to be granted multiple privileges.

35 Nuovo, The Book Trade in the Italian Renaissance, 222.

36 Between 1469 and 1530, 267 privileges were granted to 169 different individuals. They are preserved in the following archival collections: ASVe, Collegio, Notatorio; Senato, Deliberazioni, Terra; Consiglio dei Dieci, Deliberazioni; Capi dei Consiglio dei Dieci, Notatorio. This does not take into account the printing authorizations that are also found in these registers.

37 I decided not to undertake a lexicological analysis for several reasons. The texts are written in Latin or Venetian, which makes their combined treatment difficult. The Latin itself is very colloquial and the spelling by no means fixed. Moreover, for the purposes of this study, the precise analysis of terminology is not always useful except in some very specific cases, such as the use of “competition.” This kind of analysis is easily carried out without using quantitative lexicology in the technical sense.

38 It would be interesting to make a comparison with documents from other Venetian trades. However, printing is the only industry for which such a wealth of sources is available; if the contents of these registers is any indication, in years of high demand the granting of privileges for the printing and selling of books could represent one of the principal occupations of some councils.

44 ASVe, Collegio, Notatorio, reg. 14, image 312, April 18, 1497: “Not wanting, having printed the said work at very great expense and effort, that a competitor should have it reprinted and then sell it for next to nothing, as often happens, which would lead to the ruin and damage of the supplicant.” (“Non volendo, che dapoi che cum grandissima spesa et faticha l’havera facto stampar le dicte opere che qualche altro a concorrentia le fesse restampir et poi le vendesse a vil pretio come molto vole achade, che tornaria a ruina et damno de lui supplicante.”)

45 Some authors have noted the use of this term in privileges at an extremely early stage: Paolo Trovato, Con ogni diligenza corretto. La stampa e le revisioni editoriali dei testi letterari italiani (1470–1570) (Bologna: Il Mulino, 1991), 46.

46 ASVe, Collegio, Notatorio, reg. 14, image 275, February 25, 1496: “Fearing, as the supplicant does, that he may be competed with out of envy and that others may profit from his secrets and efforts.” (“Temendo lui supplicante che per invidia non li sia facto concorrentia, et che altri habia el fruto di sui secreti et fatiche.”)

47 ASVe, Collegio, Notatorio, reg. 14, image 276, February 10, 1496: “that others may not compete with him by printing it, and the fruit of his efforts and his very high expenses thereby be taken away from him.” (“Che altri emuloi fazandolo stampar li fesseno concorrentia, e cussi a lui fusse levato el fructo de le fatiche e spexe sue grandissime.”)

48 Lowry, The World of Aldus Manutius, 81–82.

49 For example: ASVe, Collegio, Notatorio, reg. 15, image 165, November 27, 1502.

50 This is the case in the privileges, but also in other documents where testimonies of printers are reported, for example ASVe, Giudici di petizion, Sentenze a giustizia, b. 159, fol. 47, November 6, 1473: “the practices of this art” (“i pratichi de questa arte”); b. 168, fol. 19, June 19, 1478: “some practices of this trade” (“qualche praticha del mestier”).

51 ASVe, Collegio, Notatorio, reg. 14, image 346, March 14, 1498: “per non esser ruinato dalla perfida ravia de la concorrentia consueta fra questa miserabel arte.”

52 ASVe, Collegio, Notatorio, reg. 16, image 18, June 18, 1508: “esso supplicante teme esser e ruinato dala perfida concorrentia, laquale regna in questa povera et miserabel arte, che seria total ruina de casa sua, laqual concorrentia solum mediante lo adviso et benigna gratia di questa Serenissimo et sapientissimo conseglio potra fugera.”

For Scholastics the place of competition in the just price was the subject of debate, but it seems to have been established as far as the Thomistic school is concerned.

56 The term does not seem to have been used in petitions for invention privileges prior to printing, but this requires further investigation.

For a more general view, see Catherine Kikuchi, “Venise et le monde du livre, 1469–1530” (PhD diss., Université Paris-Sorbonne, 2016), chap. 8, pp. 423–98, and chap. 9, pp. 499–550; these two chapters offer an analysis of socialization in Venice and in the book world, and its consequences for the formation of a professional book sector.

71 The information contained in the colophons is collected in the systematic list compiled by Paul Needham, “Venetian Printers and Publishers in the Fifteenth Century,” in Anatomie bibliologiche. Saggi di storia del libro per il centenario de La bibliofilía, ed. Luigi Balsamo and Pierangelo Bellettini (Florence: L. S. Olschki, 1999), 157–200. For the sixteenth century, I refer to Fernanda Ascarelli and Marco Menato, La tipografia del ’500 in Italia (Florence: L. S. Olschki, 1989); Ester Pastorello, Tipografi, editori, librari a Venezia nel secolo xvi (Florence: L. S. Olschki, 1924).

72 I have completed this information where it is known that particular collaborations existed, but have limited these to names that already appear in the colophons of the period studied. I have only considered economic partnerships, not literary collaborations. These relationships have been studied using the methods of social network analysis: see Catherine Kikuchi, “Utiliser les réseaux pour comprendre le développement de l’imprimerie à Venise, 1469–1530,” Essais. Revue interdisciplinaire d’humanités, forthcoming; Kikuchi, “Venise et le monde du livre, 1469–1530,” 139–44, 145–58, and 205–8. Given the difficulty of precisely dating the beginning and end of collaborations, it is assumed that a collaboration existed for the duration of the joint activity of the two stakeholders. The analyses cover long periods, as a synchronous analysis is subject to many hazards. For a seminal work on social network analysis in medieval history, see John F. Padgett and Christopher K. Ansell, “Robust Action and the Rise of the Medici, 1400–1434,” American Journal of Sociology 98, no. 6 (1993): 1259–319; Isabelle Rosé, “Reconstitution, représentation graphique et analyse des réseaux de pouvoir au haut Moyen Âge. Approche des pratiques sociales de l’aristocratie à partir de l’exemple d’Odon de Cluny († 942),” Redes. Revista hispana para el análisis de redes sociales 21, no. 5 (2011): 199–272. A group of doctoral students have also highlighted the use of social networks in history: Nikita Dmitriev, Ségolène Maudet, and Pierre Verschueren, eds., “Analyser des réseaux. Pourquoi? Comment?” thematic dossier, Hypothèses 19, no. 1 (2016): 177–252.

73 A “biconnected component” is a network where the density of links and interactions means that no member is dependent on a single individual for their attachment to the whole.

76 In terms of network analysis, a k-core is a core whose members are all related to k members of the group, where k is a numerical value. In other words, members of a 4-core have relational links with at least four other members.

77 Lazega, “Théorie de la coopération entre concurrents: organisations, marchés et analyse de réseaux,” 537–38.

78 The question here is complicated, because collaborations were not symmetrical: one person provided the funding, another the material and technical capital. It must be assumed that the printer who collaborated with several publishers was just as central and important as the publisher who provided investment to the community. The balance of power was less favorable to the former, but the fact that they were regularly chosen to produce editions testifies to their key role in a competitive environment. The prestige of certain printer-typesetters meant that this asymmetry did not pose an insurmountable problem.
