Where do I get a CiteULike Group ID?

There are two ways to add a citeulike bibliography to your project on Overleaf:

1. Enter your user name to include all of the references in your citeulike library in the .bib file on Overleaf.
2. Enter a group ID to include all of the references in a public citeulike group.

A citeulike group is a collection of references that can be shared between multiple citeulike libraries, so it's a great way to keep the references that are relevant for a particular project together in one place.

Each group has a numeric ID, and if you go to your group's page on citeulike, you can find it at the bottom of the page:

Then you can enter the numeric ID (19208, in this example) when you add the citeulike bibliography to your project:

Note that you can change the 'name of the file in this project' to something more descriptive, if you like.
