Woytek 2022a, p. 379, 380-381: "Among the momentous manuscript volumes in Eckhel’s hand preserved in Vienna, three books in modest, but durable half-leather bindings, whose boards are covered in 18th century monochrome (red or brown) marbled paper, stand out because of their in-folio format (archives nos. 79–81). Stylistically, their bindings are very similar to that of the quarto notebook no. 7, described above. These three folio notebooks – highly diverse in character between themselves – are dedicated to three different classes of ancient coins. All are characterised by more or less generous right- or left-hand margins left blank for additions and corrections; this is a feature they share with the quarto notebooks nos. 5–7, incidentally. ... No. 80 is quite different. It is inscribed "Moneta Romanorum” on the first page, where it also says: “De hac agetur sectionibus binis”; thereafter follows a short general characterisation of these two sections, the most important part of which is a definition of the somewhat ambiguous term “numi consulares”. This notebook, the pages of which are numbered sequentially in Eckhel’s hand (up to p. 239), unlike those of volume no. 79, contains material on various aspects of Roman Republican coinage, to be used for volume 5 of the Doctrina that was to deal with the “numi consulares et familiarum”, as Eckhel put it in 1795. Apart from notes for or drafts of introductory chapters, the volume most importantly contains, on pp. 81–230, a basic draft for the “Catalogus familiarum”: the alphabetic catalogue of pre-imperial Roman coins with personal names, ordered according to gentes. This central part of notebook no. 80 was made immediately accessible by cutting off the lower corners of the pages (fig. 3). It is possible to recognise the draft preserved in Eckhel’s notebook in the final version published in the Doctrina, although, both for the introductory chapters and the discussion of the coinage, the text seems to have been rewritten completely. The text in volume no. 80 is partly crossed out vertically – doubtless by Eckhel himself, exactly as in notebook no. 7 described above, in order to mark content that had been transferred to the final manuscript, when he prepared the latter, rephrasing the original text. For example, the crossed-out text on p. 3 of notebook no. 80, under the headline “De Magistratu A. A. A. F. F. stante republica”, may be seen to have provided the basis for the beginning of chapter V of the Doctrina, entitled “An ad solos IIIviros pertinuerit monetae negotium”.
