    Abstract
    Typographical errors can block access to records in online catalogs; but, when a word contains a typo and is also spelled correctly elsewhere in the same record, access may not be blocked. To quantify the effect of typographical errors in records on information retrieval, we conducted a study to measure the proportion of records that contain a typographical error but that do not also contain a correct spelling of the same word. This article presents the experimental design, results of the study, and a statistical analysis of the results.We find that the average proportion of records that are blocked by the presence of a typo (that is, records in which a correct spelling of the word does not also occur) ranges from 35% to 99%, depending upon the frequency of the word being searched and the likelihood of the word being misspelled.

    Abstract
    In bibliographic records, catalogers use the error indicators [sic] or [i.e.] with a correction to indicate that a preexisting error was noted on the item being cataloged that did occur not during the cataloging process. This article analyzes this practice and provides examples of the recent use of the error indicators. The article also suggests how the use of the error indicators in bibliographic records might be improved and describes aspects of their use that merit further study.
