Reference entries are listed in alphabetical order by the first significant word in the entry; typically, this is the first author’s last name. If the first element is the name of organization, group, or title, alphabetize by the first significant word of the name, i.e., ignore “The” and “A.” For example, an entry starting with “A puppy may reduce stress and save your life” is sorted as starting with “puppy”. Use full names for organizations and groups, not abbreviations.

If you have more than one work by the same author (or authors in the exact same order), list them in order by the year of publication, starting with the earliest. Entries for the same author with (n.d.) as the date are listed before those with a date; entries with (in press) as the date are listed after those with a date.

When an author appears both as a sole author and, in another reference entry, as the first author of a group, list the one-author entries first.

References that have the same first author and different second and/or third authors are arranged alphabetically by the last name of the second author or the last name of the third if the first and second authors are the same.

If you are using more than one source by the same author (or the same group of authors listed in the same order) published in the same year, organize them in the reference list alphabetically by first significant word the title of the article or chapter. Then assign letter suffixes after the year, e.g., 2019a, 2019b.
