For anything but exact bibliographical description it is better to take no account of the fold of the sheet, but either to give the size in centimeters or to use the notation of the American Library Association (see APPENDIX III, p. [115]), which is founded on measurement.
- FE, anything less than 10 centimeters.
- TT, anything between 10 and 12½ centimeters.
- T, anything between 12½ and 15 centimeters.
- S, anything between 15 and 17½ centimeters.
- D, anything between 17½ and 20 centimeters.
- O, anything between 20 and 25 centimeters.
- Q, anything between 25 and 30 centimeters.
- F, anything over 30 centimeters. centimeters.
- F4, anything over 40 centimeters.
- F5, anything over 50 centimeters.
- And so on.

197. Maps may be identified either by giving the scale or by measurement.
The measure (in centimeters) should be taken from the inner margin of the degrees, unless the map extends beyond it, in which case measure to the farthest point; pictures at the side are not to be included in the measure unless they come within the degree-mark. The perpendicular measure to be stated first, then the horizontal. {78}
E. CONTENTS AND NOTES.
198. Give (under the author) a list of the contents of books containing several works by the same author, or works by several authors, or works on several subjects, or a single work on a number of distinct subjects, [63] especially if the collective title does not sufficiently describe them. [64]
[63] As a collection of lives.
[64] Only Full can give the contents of all such works, including the memoirs, transactions, etc., of all the learned societies. And in an analytical catalogue this is much less important. When every separate treatise is entered in its proper places under the names of its author and of its subject, why should it be given again in a long column of fine type which few persons will ever read? Because, if analysis is not complete, contents supplement it; and one who has forgotten author and subject may occasionally recall them by looking over a “contents;” and this list is, so far as it goes, a substitute for a classed catalogue in this respect. Moreover, the “contents” is needed to fully explain the character of the subject-entry (see § [4]). In the division Biography under countries we have many such titles as “Memoirs of eminent Englishwomen,” “British senators,” “Political portraits.” It is an advantage to the reader, though perhaps neither a great nor a frequent advantage, to be able to find out from the catalogue what Englishwomen and what British senators he shall find described in the books. No catalogue can be considered complete that omits such information.
For collected works of any author “contents” have been found so useful that even Short often gives them, especially of late, and strange to say, not rarely prints them in the most extravagant style, allowing a line for each item. One may sometimes see a quarter of a page left bare from this cause.
