Recent studies have shown significant advancements in renewable energy technologies [1]. Solar power, in particular, has seen a remarkable increase in efficiency due to new photovoltaic materials [2]. These materials have not only improved performance but also reduced costs [3]. Furthermore, wind energy research has revealed innovative turbine designs that maximize energy capture [4]. Interestingly, similar advancements were noted in earlier studies, confirming the trend towards more sustainable energy solutions [5]. In another investigation, solar power's impact on reducing carbon emissions was thoroughly examined, highlighting its potential in combating climate change [6]. Further studies on wind energy also supported these findings, demonstrating the growing importance of renewable sources [7].

If these references were cited again later in the document, they would be assigned new numbers, ensuring clarity and consistency in the citation process.

To insert numbered references in EndNote that assign a new number even for repeated citations, you'll need to customize the citation style you're using.

Follow a step-by-step guide to achieve this:

Open EndNote and go to the Edit menu.

Select Output Styles, then choose Open Style Manager.

In the Style Manager, find and select the style you are using (e.g., "Numbered").

Click the Edit button to open the style editor.I

n the style editor, go to the Citations section.

Select Templates.

Under the "Templates" section, you should see the current format for your citations. Make sure it uses a number format (e.g., [#] or superscript).

Next, go to the Citation section and select Repeated Citations.

Change the setting from "Same As First" to "Same As First (change number)". This option ensures that repeated citations are given a new number each time they are cited.Save the modified style with a new name to avoid overwriting the original style.

Close the style editor and return to your EndNote library.

Apply the new style to your document.

I hope this shall help .

Dear Hendricks. I appreciate very much your response! I followed your advice and was able to make it as far as changing the setting for the "repeated citation" format when I edit an output style in EndNote. As the base style, I am using "Numbered". The problem is that the option to change settings for "repeated citation" only appears on the left menu of the Style Manager under the "Footnote" category. Furthermore, when I apply this style to my Word document, the references appear in numbers but are not assigned a new number when repeated. I am using a Mac and have attached a screenshot of the settings I am able to choose, and what I have chosen so far. Do you have any further ideas on what I could do to achieve my goal of assigning a new number to repeat citations for an endnote (and not a footnote)? Thank you so much for your time. I have also attached the example document I am working with.

Dear Gregory Trencher, to ensure that citations in EndNote are repeated correctly without creating footnotes, you can follow a straightforward process. First, insert citations in your document using EndNote's "Insert Citation" feature. When you need to cite the same source again, simply insert the same citation at the desired location without re-adding it to EndNote. Ensure your document is set to the appropriate citation style by navigating to "Edit" > "Output Styles" > "Open Style Manager" in EndNote and selecting the desired style. This will ensure consistent formatting for repeated citations. If necessary, customize the citation style by editing the citation templates under "Citations" > "Templates" in the style editor, specifying how repeated citations should appear. Finally, use the "Update Citations and Bibliography" feature in your document to apply the correct formatting throughout. This method ensures that your citations are repeated accurately within the text, without generating footnotes.

I hope this will help you, I wish you success.
