The corresponding definition in late editions of Webster's Dictionary is:
An emblem, usually a device assumed by the publishing-house, placed either on the title page, or at the end of a book.
In what subtle way this secondary and inadequate definition has crept into American usage we do not know, and we plead earnestly for its abandonment.
In the encyclopedias consulted, there is nothing disturbing, the definition of the Encyclopaedia Britannica, written by Dr. Pollard, being especially clear and concise. It runs in part as follows:
... a final paragraph in some manuscripts and many early printed books, giving particulars as to authorship, date and place of production, and sometimes expressing the thankfulness of the author, scribe or printer on the completion of his task ... the importance of these final paragraphs slowly diminished, and the information they gave was gradually transferred to the title page. Complete title pages bearing the date and name of the publishers are found in most books printed after 1520, and the final paragraph, if retained at all, was gradually reduced to information as to the printer and date. From the use of the word in the sense of a "finishing stroke" (from the story that the final charge of the cavalry of Colophon was always decisive) such a final paragraph as has been described is called by bibliographers a "colophon," but this name for it is quite possibly not earlier than the eighteenth century.
Let us turn from general works to those specifically bibliographical. In his Introduction to Bibliography,[2] Dr. McKerrow writes: "In the early days of printing, the end of the book was the normal place for the printer's name and the place and date of printing to appear. The history of the colophon is merely that of the gradual transference of this information to the title page. When this was complete the colophon was as a rule of no use and it was abandoned."
Later, among his cataloguing instructions we find: "A colophon should always be noticed, if there is one. It is also, I think, desirable to record the occurrence of a printer's device (even without a verbal imprint) at the end of a book, as this often appears to take the place of a colophon."
Iolo Williams' Elements of Book-Collecting[3] contains this paragraph: "In the earliest printed books the title page's functions were performed by the colophon, a word which is a transliteration of the Greek, a summit or finishing stroke. The colophon is put, not near the beginning of the book, like the title page, but at the end, and it usually takes the form of a statement that here ends such-and-such a book, written by so-and-so, printed by so-and-so at such-and-such a place and date. The use of the colophon has been revived in certain finely-printed modern books, but such modern volumes usually contain both a title page and a colophon."
Though not quite as satisfying, the following allusion in Van Hoesen and Walter's Bibliography[4] should be quoted, as occurring in a modern American treatise on the subject: "The early printers used the colophon at the end of the book instead of a title page, and the colophon is still used to indicate the printing firm in cases where it is not part of the publishing firm given on the title page."
These are the latest printed words that we have noticed. Suffice it to say that we have nowhere found in earlier important manuals anything but the (to us) proper explanation of the term. In other words, we gather from important sources that, while a colophon may include or even take the form of a printer's mark or device, such a mark, placed upon a title page, is not a colophon.
