Making changes to an existing citation style, instead of replacing it with a new one, is an advanced process that requires prior knowledge on how to do it. To modify a citation style 18 steps:

Steps 1-2-3-4: Visit the csl.mendeley.com (1) > click on Search by name (2) > enter keywords (3) > Edit (4) (Login to mendeley.com account, if prompted).

Steps 5-6-7: Choose section to edit (5) > make changings here (6) > preview results here (7).

Steps 8-9: When you completed the changes on the style, click on Style (8) > Save Style (9). Style saved to mendeley.com

Steps 10-11: Click on Info (10) > copy the URL of ID (11).

Steps 12-13: Click on + Add references (12) > Set up watched folder (13).

Steps 14-15: Click on Formatted Citation Style (14) > Select another style (15).

Steps 16-17-18: Click on Add custom style (16) > paste ID URL (17) > Add (18).

Editing any citation style and setting it on the Mendeley Reference Manager process is completed as stated below.

Alternatively, you can use the Code editor on csl.mendeley.com to create or modify a citation style manually (citationstyles.org, 2026).

If a suitable style is not found among the 10,000+ available in csl.mendeley.com you can:

• Create a style from scratch
• Or modify an existing one by using:
• csl.mendeley.com (created by Mendeley)
• editor.citationstyles.org (joint venture)
• www.zotero.org/styles (is maintained by volunteers led by George Mason University)

All three use CSL (Citation Style Language) and are compatible across multiple reference managers.

Creating a style from scratch is time-consuming. It's recommended to find a similar style and edit it instead. The section titled “iii) Editing Any Citation Style” briefly covers the basics of modifying a citation style file. (citationstyles.org, 2024
