tten (who, like the writer, are of modest
means), I forbear to enter upon it in detail.

[56] It is a tedious game, but a very necessary one, and is a service due
to an author. In entering a long list of errata in a folio book which has
many lines to the page (Cotton's 'Monluc' has 62 lines, and the 1707
edition of Sandford's 'Genealogical History of the Kings and Queens of
England' has nearly 150 errata!) the following method saves a lot of
time. Take a strip of paper about an inch wide, place it on a page, and
make a dash on the strip at every fifth line of text, numbering the
dashes 5, 10, 15, 20, etc. This measurer saves one counting the lines
every time.

1893, p. 31, where there is also an illustration of it. For Caxton's
advertisement, see an excellent article upon these early catalogues, by
Mr. A. W. Pollard, in 'The Bibliophile' for March 1908 (vol. 1. No. i, p.
22).

[60] A collection of thirty-two facsimiles of these fifteenth-century
book advertisements was published by Herr Konrad Burger in 1908.

[61] This is not strictly accurate, for there were agents or booksellers
(call them what you will) who bought and sold manuscripts at Rome in very
early times. A document dated 1349 (quoted by Laborde, 'Les Ducs de
Bourgogne,' tom. 1, p. 459) mentions one Thomas de Maubeuge, 'bookseller
at Paris,' who sold a volume to the Duke of Normandy for fourteen florins
of gold.

[63] Mr. E. G. Duff, _op. cit._ Beckmann has 12,475, quoting Fabricius'
'Bibliotheca Latina,' ed. 1772, vol. iii. p. 898, where the document is
printed in full.

Camb. Hist. Eng. Lit. vol. iv. chap, xviii., 'The English Book-trade,' by
Mr. H. G. Aldis.

[66] Curwen's 'History of Booksellers,' 8vo, 1873, deals chiefly with the
later English houses; while Mr. E. Marston's 'Sketches of Booksellers of
Other Days,' 12mo, 1901, is concerned only with eight London booksellers,
from Tonson to Lackington. Mr. F. A. Mumby's 'The Romance of
Bookselling,' 8vo, 1910, contains a bibliography of the subject, but says
little about the early continental book-marts. Mr. W. Roberts' 'Earlier
History of English Bookselling,' 8vo, 1892, deals with London alone, and
does not help us. There is a short article on
