Consistency studies have discussed the relationship between indexing consistency and exhaustivity, and it commonly accepted that higher exhaustivity results in lower indexing consistency. However, this issue has been oversimplified, and previous studies contain significant misinterpretations. The aim of this study is investigate the relationship between consistency and exhaustivity based on a large sample and to analyse the misinterpretations in earlier studies. A sample of 3,307 monographs, i.e. 6,614 records was drawn from two Chinese bibliographic catalogues. Indexing consistency was measured using two formulae which were popular in previous indexing consistency studies. A relatively high level of consistency was found (64.21% according to the first formula, 70.71% according to the second). Regarding the relationship between consistency and exhaustivity, it was found that when two indexers had identical exhaustivity, indexing consistency was substantially high. On the contrary, when they had different levels of exhaustivity, consistency was significantly low. It was inevitable with the use of the two formulae. Moreover, a detailed discussion was conducted to analyse the misinterpretations in previous studies.
