acta (ăk´tə), official texts of ancient Rome, written or carved on stone or metal. Usually acta were texts made public, although publication was sometimes restricted. Acta were first posted or carved for general reading c.131 BC They were accounts of general interest and were later called Acta diurna, and they have been compared to modern newspapers. There were special acta of municipal, legal, or military content. The Acta senatus, according to a Roman administrative tradition, were for many years kept secret so that the public should have no knowledge of senatorial debate. In 59 BC, Julius Caesar, as consul, ordered their publication along with the Acta diurna, but later the publication was censored. Acta was also the term used for the laws themselves, primarily those promulgated by the emperors.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
