How to show all authors instead of Et al

Hello,
I want to show all the authers instead of et al.
Could you tell me how?

Thanks

Welcome to the forum, @Yuji_Endo. Showing all the authors in the reference list will depend on the citation style you select. A citation style that might work for you is Elsevier-Harvard (with titles), which lists all authors of the references in the bibliography.

We get 8000+ citation styles from the online repository CSL and you can search styles by example there. Existing citation styles can be modified to your needs using their online editor available at editor.citationstyles.org.

If the style above isn’t suitable for your needs and you decide to modify an existing style, please download the new CSL file to your computer and upload it to Paperpile via Settings > Citation Styles. It will then be available to use in Google Docs and Word.
