line feed

line feed (LF)
1. A format command for printers and displays, signaling the requirement that the data that follows should be printed or displayed one line pitch below the preceding data. In impact printers it invokes the physical movement required to move the paper at right angles to the print line by a distance equal to the previously specified pitch between printed lines. In nonimpact page printers it invokes an analogous action in the stored image that is subsequently transferred to the paper in a continuous movement.

2. A format command that with some operating systems is used to terminate a line of input and an implicit CR (carriage return) actioned so that the next input is displayed/printed at the start of the next line.

Learn more about citation styles

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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
