Include only abbreviations used in the text being indexed (ie, if a text uses only an expanded form, eg, National Institutes of Health, but never the abbreviation, do not include “NIH” in the index).

Abbreviations are listed alphabetically among other entries (examples from Thomas9,10).

  • catheterization

  • CAT scan. See computed tomography

  • cat-scratch disease

  • CEA (carcinoembryonic antigen)

  • cecum

  • ectopic ACTH syndrome, 106, 107, 109

  • ectopic kidney, 2226

  • ectopic pregnancy, 1947, 2055–2056

Identical abbreviations are sorted by case; be consistent throughout the index, eg,

  • HeV, 232

  • HEV, 330–331

  • PaO2, 464

  • PAO2, 251

Use cross-references and expansions with abbreviations, as in these examples (first set from Thomas9).

  • CAT scan. See computed tomography

  • computed tomography (CT, CAT scan), 2715–2716

  • CT. See computed tomography

  • mitral stenosis (MS), 497

  • MS. See mitral stenosis; multiple sclerosis

  • multiple sclerosis (MS), 497

The following example illustrates (1) a cross-reference with an abbreviated organism name and (2) use of roman cross-reference term (See) when entry terms are in italics.

E coli infection. See Escherichia coli infection

When an abbreviation is more familiar than the expansion, index under the abbreviation1,2; include the expansion in parentheses, use a cross-reference to the abbreviation from the expanded term, or both.4 Terms in this manual for which it is specified that the abbreviation may be used without expansion (see chapter 14.0, Abbreviations, and chapter 15.0, Nomenclature) should probably be indexed under the abbreviation. However, terms expanded at first mention, as recommended in this manual, may nevertheless be more familiar in their abbreviated form. Usage in the text being indexed is a guide to which form is more familiar.

deoxyribonucleic acid. See DNA

DNA, 112, 334, 556–560
