Referencing guide for APA 7
APA (American Psychological Association) is a referencing style common within the fields of psychology and health sciences. APA is a so-called author-number style. The bibliography should be placed at the end of the document, be arranged alphabetically by authors' last names and should contain all necessary bibliographic information. The in text, references should contain the author(s) and the year of publication within parenthesis.
KIB:s guide for APA is especially for students at Karolinska Institutet. The references should be considered as recommendations based on APA 7 and in some cases with the support of Swedish cataloging rules for libraries. The guide for APA 7 was first published in 2020.
Always ask your supervisor or teacher which style to use and be consistent in your text. When in doubt, double check with official manuals, contact the library for support and discuss with your supervisor or teacher at KI before submitting your thesis or assignment.

- Please see the examples for books to find more information about how to refer to webpages and websites with several creators.
- When a URL is long or complex, you may use shortened URLs if desired, as long as you check the link to ensure that it takes you to the correct location.
- Include a retrieval date if the contents of the page are designed to change over time and the page itself is not archived. Set the date between website name and URL as follows: Retrieved Month date, year, from (Retrieved October 23, 2020, from http://...)
- Dates are based on when the website was last updated. Specify date as precisely as possible. If only year is available, use only year. If no publication year is available, use (n.d.), short for no date, instead, in text and reference list.
- If there is an established and well-known abbreviation for an authority, department or organization, you can use this together with the name in full the first time the reference is mentioned. After this, you only use the abbreviation. If the full name is short or if the abbreviation is unknown, it is better to write the full name each time.
- If you use more than one webpage from the same website, create a reference for each page.
- In addition to webpages, such as the one above, websites can host several different types of documents, for example reports, pdf-files or books. You refer to these in the same way as to the printed versions, but also add URL or DOI at the end.
- If there is a reference to an entire website in the text, the website is not included in the reference list, only in the text, and the URL to the entire website must be stated. For example “We used Padlet (https://padlet.com) for our questionnaire”.

- The date of a computer software or mobile app reference is the year of publication of the version used.
- The date of an AI-tool is the year of the version you used. You need to include only the year, not the exact date. The version number provides the specific date information a reader might need.
- If no publication year is available, please use (n.d.), short for no date, instead.
- You should never use a text generated in an AI tool as your own, but AI generated material can be used as e.g. study material or basis for discussion. Whenever you paraphrase, quote, or incorporate into your own work any content from a generative AI tool (whether text, image, data, or other) make sure you cite the tool you used to create it.
- AI generated material is always unique, therefore it is a good idea to copy the material (prompt and generated material) as an attatchment to your work.

More information
- The Graham example is structured similarly to the reference for a chapter in an edited book because the entry has an individual author, the encyclopedia has an editor and the whole book has a publisher. Because this version of the entry is archived, a retrieval date is not needed.
- When an online reference work is continuously updated and versions are not archived, use “n.d.” as the year of publication and include a retrieval date.
- If you have two or more “no date” references with the same authors in the same order, you should use lowercase letters – a, b, c, and so forth – after the publication date and alphabetize the references by their titles (for example: National Library of Medicine (n.d.-a) use the term…).

- Most Swedish laws and regulations are now available electronically on the Internet. Laws and regulations may be changed and updated, and you should check the latest edition.
- It is possible to state chapter and paragraph in the text.
- If there is an established and well-known abbreviation for the law, you can use this together with the name in full the first time the reference is mentioned.

More information
- Arrange entries in alphabetical order by the surname of the first author followed by the initials of the author’s given name(s).
- The same rules apply to books with editors and when an organization is author. References without author and editor are sorted alphabetically based on title.
- One-author entries precedes multiple-author entries beginning with the same first author, even if the multiple-author work was published earlier. Multiple-author entries with the same first author and different subsequent authors should be arranged alphabetically by the surname of the second author, or if the second author is the same, the surname of the third author, and so forth.
- To differentiate references with the same author and the same year, put a lowercase letter after the year in both the in-text citation and the reference list entry. If the references are in press or have no date, add a hyphen before the letter (n.d. –a) (n.d. –b).

- If there are more authors than mentioned in the citation, et al. is added. Please note that et al. means "and others" and can't replace one single author. If only one author remains you should therefore state the name of this author as well.
- The same rules apply to books with editors and when an organization is author. References without author and editor are sorted alphabetically based on title.

Studies indicate that lung cancer may grow more slowly in women. Lindell et al. (2015) showed that 85% of the lung tumours that took more than 400 days to double in volume were found in women. This result is a reflection of the higher incidence among women of forms of cancer with a slower disease progression such as alveolar cell carcinoma and adenocarcinoma, but Lindell et al. found that the time it took for the volume to double was greater in women, regardless of the histological type of lung cancer.
Lindell et al. (2015) studied four different histological types of lung cancer.
More information
- If a citation recurs in the same paragraph, you may omit the parentheses with the year if the author is mentioned in the text. If you don't mention the author in the text you should always include both author and year in the parentheses.

The Phurnacite factory in Abercwmboi killed all the trees for two miles around. We’d measured it on the mileometer. It looked like something from the depths of hell, black and looming with chimneys of flame, reflected in a dark pool that killed any bird or animal that drank from it. The smell was beyond description. (Walton, 2010, p. 11)
