Text Headings Headings should correspond exactly to the headings in the Table of Contents. However, long parenthetical or qualifying remarks can be deleted from the Contents. Centered, initial capital letters and the rest lower case. If needed, an additional level of heading can be inserted subordinate to the last centered heading, but superior to the final run-in heading. It is formatted flush left but not run into subsequent text.
Preferred format is initial capitals and lower case or initial capitals and small capitals.
If a series of centered headings is needed to specify taxonomic classification of a subject, it is preferable to type such taxa in all capitals. Do not use the space bar. Use indentation commands to format indented text lines, lists, etc., such as the reference section in AMNH publications. Use these commands rather than tabs. If tabs are used to indent successive lines of text, they must all be removed before the file can be typeset.
