2. A second important drawback is that information may be lost to the index user if citations are merely copied from the source literature without any effort at verification of the accuracy of the cited reference. Published references often contain typographic errors and bibliographic inconsistencies3 which affect the automatic sorting of index entries and which result in entries being published incorrectly in index positions where the user would not look for them.
