Ketchikan (kĕ´chĬkăn´), city (1990 pop. 8,263), SE Alaska, a port of entry on Revillagigedo Island in the Alexander Archipelago. A supply point for miners in the gold rush of the 1890s, it has become a center of Alaska's fishing industry (especially salmon, halibut, and abalone). Its logging, and pulp industries are declining, but tourism adds to the economy. There are major molybdenum deposits nearby. Its excellent ice-free harbor on Tongass Narrows makes it an important port on the Inside Passage and a distribution point for a large area. The headquarters of Tongass National Forest are in Ketchikan, and Dolly's House Museum preserves some of the 20 brothels that operated in the city until 1954.

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:

  • 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.
