at he has no hesitation in recommending it. First of
all he procured a card-index box capable of holding about a thousand
cards. Upon these he entered the books as he came across them in
catalogues of all sorts, under the authors' names. Thus:

DIAGO (FRANCISCO)
Historia de los Antiquos Condes de Barcelona
Fo: Barcelona, 1603.

After each he generally pencils the price and bookseller, or other
authority for the book's existence; but this is for his own guidance
only, and is by the way. A fresh card is used for every book. This forms
a rough index of every work upon his subject with which he is acquainted.

Now for the bibliography proper. For this our bookman uses single sheets
of paper, eight inches by five, ruled with feint lines. These are
contained in a 'spring-back' portfolio, thus forming a handy volume in
which pages can be inserted anywhere at will. At the top of the page he
writes the author's name, just as for the index, and beneath this
(leaving a line blank) he copies the title-page of the book _in extenso_,
using red ink for red print, capitals where capitals occur, and
underlining those words which are in italics. The end of each line is
indicated by a vertical stroke. Then follows a complete collation of the
book. The following illustration, however, will convey a better idea than
can be given in words. It will be noticed that after the size (which is
given in the English notation) the measurement _of the title-page_ in
millimetres is added within parentheses. If more than one copy has been
examined this measurement is of the largest. The reason why the
form-notation is given as well as the actual size, is because it is
easier to carry the form-notation in one's head.
