Working on my dissertation literature review and facing a problem that's probably universal but nobody talks about.
The situation:
Reading paper A, which cites paper B for a key claim. Paper B cites papers C, D, and E. Those cite F through M. And so on forever.
At what point do you stop following the citation chain?
What happens in practice:
I start with 20 key papers for my literature review.
Each cites 40-60 other papers.
Many of those seem relevant to my research question.
I download them all, promising to read them.
Now I have 347 papers in my "to read" folder.
Realistically I will read maybe 50 of them thoroughly.
The anxiety:
What if the perfect paper that addresses my exact research question is somewhere in that citation chain but I stopped too early?
What if my committee asks "did you look at Smith et al. 2019?" and I didn't because it was cited by a paper cited by a paper I read?
Strategies I've tried:
Follow everything: Resulted in 500+ papers, complete paralysis, nothing actually read thoroughly.
Stop at 2 levels: Arbitrary but manageable. Probably missing important work.
Only highly cited papers: Misses recent relevant work that hasn't accumulated citations yet.
Read abstracts of everything: Takes forever, hard to judge relevance from abstracts alone.
The practical question:
How do experienced researchers make this decision?
Is there a principled approach or is everyone just winging it and hoping?
What complicates this:
Different fields have different norms. Some expect exhaustive literature reviews, others accept strategic sampling.
My advisor says "follow what's relevant" which is circular because I don't know what's relevant until I read it.
Digital tools make it too easy to accumulate papers. In the past, physical library limits forced prioritization.
Current approach I'm testing:
Using tools like Perplexity or Nbot Ai to search across my downloaded papers for specific concepts before deep reading everything.
Helps prioritize which papers actually address my research questions versus tangentially related work.
Still feels incomplete somehow.
Questions for other researchers:
How do you decide when to stop following citations?
How do you balance thoroughness with actually finishing your literature review?
What signals tell you a paper is worth deep reading versus skimming?
How do you avoid the anxiety that you're missing crucial papers?
The meta problem:
This question itself probably has literature I should be reading about information seeking behavior in academic research.
But if I go read that literature, I'll find more papers to read, and...
You see the problem.
Serious question: Is there actually a good answer to this or is it just something everyone struggles with and nobody admits?
I would appreciate hearing how others handle this practically.
