In the published book (1998), 238 entries have TA codes that were used for one or more previous entries. Thirty instances were gender-specific homologues, 150 represented the same entity with identical text entries (including three that displayed the addition of a gender symbol), 51 represented the same entity but with differences in the Latin and/or English terms, and seven instances were associated with errors. In the online TA98, all entries sharing a TA code have the same Latin and English terms, except gender-specific homologues. The resolutions for the seven errors are described below.
