A good way to stay up to date on papers that are of interest to you. Find some papers that are very well cited that talk about your particular topic, and use reverse citation on google scholar and then sort by date.
Eg, I’m interested in RAG and this paper is one of a few is that is very well known and would likely get cited by something I’m interested in.
I have quite a few that I cycle through, as folks don’t always remember to cite these root papers.
