(introduction...)

Manuscripts should be typed in double line spacing for easy and quicker reading and to allow legible and clear corrections to be inserted. Several copies are usually provided for the readers. To improve presentations of text, sample models of page lay-out exist, space being foreseen, for example, for standard pages, two column pages, or pages with margin notes. These models facilitate the work of composition and lay-out.

There should be wide margins on the left hand side, the top and the bottom of the page for evaluators' annotations, and typographical instructions.

All pages should be typed on one side only and of uniform length.

Pages should be numbered consecutively from the first to the last page of the text and should be well separated from the body of the text.

Titles of chapters and sub-chapters should be typed in capital letters and stand out from the body of the text, quadruple interline spacing being used. Subtitles should be aligned on the left and typed in triple line spacing. The location of illustrations should also be quite clearly indicated.

The summary at the end of a lesson or chapter can be presented in a "frame" to better retain the reader's attention.

Italic type in printed publications is indicated by underlining and should be used sparingly i.e. foreign words and words and phrases of paramount importance. For content which should be underlined in the printed book, words or phrases can be circled in pen and "underline" written in the margin.

A chapter, a lesson or an important section of the book should always start on a new page.

Long quotations from books or documents for insertion in the text should be visible, wide indentations being provided at the left, top and bottom of the text.

A footnote or a reference should be separated from the body of the text by a line across the page.

It is preferable to limit the number of variations in a book (lettering, different chapter heads, too diversified types of illustration or changes in layout) to facilitate reading and use
