SCHOLARLY NOTATION is a type of writing used by academics and researchers to cite sources in their work. SIC is an abbreviation for the Latin phrase 'SIC erat scriptum, ' which means 'thus it was written.' IBIS is an abbreviation for the Latin phrase 'ibidem, ' which means 'in the same place.' IBID is an abbreviation for the Latin phrase 'ibidem, ' which means 'in the same place.' All three of these abbreviations are used to indicate that a source has been cited multiple times in a single document.
