Citing Mosby’s Medical Dictionary may seem challenging, because this reference work does not name an author. Both Modern Language Association and American Psychological Association styles provide for full citation of works like this, with only slight differences.
MLA Citation Style
When citing Mosby’s in the text, give the first part of the title, followed by a comma and the page number, all enclosed in parentheses: (Mosby’s, 42). Full references go at the end of the paper in an alphabetical list titled Works Cited. While the first information would normally be the author, in this case, the title goes first, since this dictionary has no listed author or editor; follow this with the edition, place of publication, publisher’s name, and year. End with the format. The full citation would look like this, using hanging indention:
Mosby’s Medical Dictionary. 9th ed. St. Louis, MO: Mosby Elsevier, 2013. Print.
APA Citation Style
For in-text citations, list the first word of the title, followed by a comma and the date of publication, all enclosed in parentheses: (Mosby’s, 2013). If you directly quote the dictionary, include the page number in your in-text citation as well: (Mosby’s, 2013, p. 42). List full citations on a page at the end of the essay, under the heading References, using hanging indentions. The first element in a work with no author or editor is the title; capitalize only the first word. Follow this with the date, edition, and publication information. The APA References list entry would look like this:
Mosby’s medical dictionary. (2013). (9th ed.). St. Louis, MO: Mosby Elsevier.
