A text search method has been developed with which errors within large data base compilations may be located if the citations contain redundant information. This study has been applied to the ASTM Infrared Spectral Index of 91 875 spectra. Each citation within the data base contains some redundant information. If the citation is correct, the redundant information is the same; if the information differs, the citation is incorrect and an error has been located. The overall error was found to be between 3 and 5% within the limits of this study. The error search is general and can be applied to most chemical data base compilations.
