The phrase “Loco citato” is often abbreviated as “L.C.” in academic and bibliographic contexts. It is used to refer to a source that has already been cited in the same document or text. When an author wants to refer to a previously cited source without repeating the full citation details, they can use “loco citato” or its abbreviation “L.C.” to indicate that the citation is from the same location or reference as previously mentioned. This is a useful way to streamline references and avoid redundancy in academic or scholarly writing.
