(in Russian, list), in printing and publishing, the unit of measure of printed output.
The author’s sheet (avtorskii list), which in the USSR is equivalent to 40,000 characters, is used to calculate the length of a manuscript.
The paper sheet (bumazhnyi list) is the unit for calculating the amount of paper required for or used in publication. It is given in terms of width and length—for example, 60 × 90 cm. The trim size of a finished book, magazine, or other publication is 1/2, 1/4, 1/8, 1/16, or other fraction of a sheet, depending on the dimensions of the paper sheet and the number of folds made in it during production. The sizes of paper sheets have been standardized in most countries. In the USSR, GOST (All-Union State Standard) 1342–68, Paper for Printing: Dimensions, specifies seven sizes for sheet paper (in cm)—60 × 84, 60 × 90, 70 × 90, 70 × 100, 70 × 108, 75 × 90, AND 84 × 108—as well as seven widths for roll paper, between 60 and 120 cm. Gost 6445–53 sets roll widths of 42 to 168 cm.
The printer’s sheet (pechatnyi list) is used to calculate the actual length of a publication; the unit of measure is a paper sheet 60 × 90 cm, printed on one side. For paper of other dimensions (for example, 70 × 90 cm), the term “actual printer’s sheet” is used. In planning and keeping records of publishing output, the length calculated in actual printer’s sheets is usually converted into standard 60 × 90 sheets by means of a factor equal to the ratio of the area of the sheet being used to the area of the 60 × 90 sheet, which is taken as 1.
The publisher’s record sheet (uchetno-izdatel’skii list) is used to calculate the length of a publication and, like the author’s sheet, is equivalent to 40,000 characters of text, 700 lines of verse, or 3,000 sq cm of graphic material. The length of a publication calculated in publisher’s record sheets includes the text of the written work itself, plus all the other textual and graphic material (editorial foreword, column numbers, running heads, and so on). Publisher’s record sheets are used in planning and record-keeping and in measuring the work of editors, production editors, and proofreaders.
