References to papers 'in press' must indicate that the article has been accepted for publication. The DOI identifier must be included as a clickable link. References to papers in preparation or submitted are not permitted. Reproducibility must be maintained.

In the text, references should be given as Rᴏɴᴋᴀʏ and Fɪʙɪɢᴇʀ (1993), or (Rᴏɴᴋᴀʏ & Fɪʙɪɢᴇʀ, 1993; Pᴀᴘᴘ, 1995), Mᴀʀsʜᴀʟʟ (1992), or (Mᴀʀsʜᴀʟʟ, 1992). When a citation includes more than two authors, e.g., Gʀᴇʏ, Bʟᴀᴄᴋ, and Wʜɪᴛᴇ, the paper should be referred to in the text as Gʀᴇʏ et al., provided that this is not ambiguous.

Internet reference

The internet is an important source of information. The clarity and reproducibility of articles should also be ensured when using internet sources. Since websites do not guarantee the permanent availability of the content displayed on the website, it is necessary to choose a service that ensures the readability of the referenced content in the long term. It is not sufficient for the author to make a backup on their own computer; the content of the page must also be made readable to the readers of the article. This can be done, for example, using the archive.org Wayback system.

To use the archive.org/web link, we paste the URL of the page to be saved into the "Save Page Now" field and click the "Save Page" button. We wait for the system to save the page. By pasting the searched link into the search field, we retrieve the saved page, the command line link of which can be copied into the references. We make the link clickable.
