There are various methods, also known as reference styles or citation styles, for clearly indicating which sources you have used in an academic text. The method you use varies depending on the subject area, and sometimes even the specific course. Discuss with your lecturer which method you should use. Each style has its own rules.
Whichever method you use, there are always two important steps:
The following diagram shows how these two steps are carried out in the different methods:
| Reference methods | ||||||
|---|---|---|---|---|---|---|
| author - year | footnotes / endnotes | volgnummers (issue??) | ||||
|
Step 1: Indicate in the text that you are using a source. |
surname of author(s) and year of publication (and page number if cited)
|
footnote/endnote number
|
sequence (issue??) number of the publication
|
|||
|
Step 2: In the reference list, provide a complete reference. |
References in alphabetical order by author name | write references in the footnotes/endnotes | References in the order in which they are mentioned in the text at the end of the report | |||
The methods mentioned are a rough classification. Within each method, there are different styles that prescribe in great detail how to create references.
In the reference list, you provide enough information about the source so that the reader has sufficient details to locate it.
The table shows which information is needed to create references, depending on the type of publication:
| Book | Chapter in book | Journal artice | Webpage2 |

1 Digital Object Identifiers (DOIs) are a series of characters that provide a permanent link to individual publications. An example of a DOI is: https://doi.org/10.1038/s43017-024-00573-7. DOIs are assigned to different types of publications, such as books, book chapters, and articles. When a DOI has been assigned, you are required to include it in the reference list.
