Concordances: Part III
It is an index, not a concordance, if it meets these standards:
Usability
- Does the index appropriately anticipate the needs of its users?
- Are the significant concepts indexed?
- Are there appropriate alternative terms for accessing concepts?
- Are special treatments such as italics and boldface appropriate to the complexity of the material and the needs of the user?
- Is there a headnote explaining special treatments?
- Does the format provide for ease in visually scanning the index?
- Is the phrasing of entries and subentries clear, with significant terms first and no unnecessary prepositions?
Coverage
- Does the index cover the ground? Does it do so in an evenhanded fashion?
- Look up a few important topics to see if coverage is adequate.
- The index should go beyond listing the main headings in each chapter or rearranging the table of contents.
- Significant concepts should be indexed, and scattered discussions of a concept should be brought together.
- Irrelevant information, such as scene-setting material or passing mentions, should not be indexed.
- There should be no apparent indexer bias.
Analysis
- Are main entries analyzed appropriately into subentries?
- Are subentries overanalyzed so that the same page numbers are repeated again and again in close proximity to one another?
- Are there strings of undifferentiated locators at an entry?
- Are the number and level of subentries appropriate to the complexity of the book?
Access
- Is there more than one access point to significant concepts?
- The index should use the author’s vocabulary but should also provide alternative terms and cross-references that will give the reader access.
- Entries should be “flipped†where necessary or appropriate.
Cross-referencing
- Are cross-references adequate and useful?
- See also references should send readers to appropriate related material. (Double-posting is preferable to Seereferences that send the reader to an entry with very few page references.)
Accuracy
- There should be no misspellings or typos, no odd page ranges or references out of order.
- Alphabetization of main entries, subentries, and cross-references should be correct.
- Punctuation should be correct.
- Forms of names and terms should be correct and appropriate to the field of specialization.
- Cross-references should neither be circular nor point to missing or differently worded entries.
- “Flipped†entries should have the same page references at both locations in the index.
Style
- Is the style consistent throughout?
- Does the style effectively resolve challenges presented by the text?
- Look at such style points as sorting order, punctuation of cross-references, leading and separator punctuation of locators, abbreviation of inclusive ranges, positioning of cross-references, run-in. vs. indented subentries, capitalization of main entries, use of alternative typefaces.
