Citing multiple Github repositories with a single citation I have reached the maximum paper length and already shortened everything as possible. I use 4 different github repositories, which I mention in my paper. Unfortunately, there is absolutely no room left to add a citation for each repository.

What options are there to solve this problem?

Would it be a good idea to create a new own repository that references the 4 different repositories and only cite my own repository?
There are really only two solutions to this problem, and which is appropriate depends on the customs of your field:


Name the repositories (and possibly give their URLs), but do not formally cite them. In some fields this will be unacceptable, others it's up to the author, and in yet while others it is considered unacceptable to cite a non-peer-reviewed source like a repository (I have had journals force me to de-formalize software citations before!).
Shrink something else to make space for the repository citations. You may think this is not possible, but I promise you that you can get the few lines you need without significantly affecting content through minor tweaks in wording, layout, and such (including in reference contents!)
