Anyone using NotebookLM for cross-referencing data across multiple reports?
I deal with a lot of recurring structured reports where the same info shows up across different documents, sometimes with small discrepancies. I've started feeding a batch into one notebook and asking targeted questions ("where do these two reports disagree on X") instead of reading everything manually.
Works better than I expected for catching mismatches, but I'm hitting limits once the source count gets large — organization gets messy fast.
Anyone found a good system for managing notebooks once you're past 15-20 sources? Curious how others structure this for ongoing/recurring work vs. one-off research.
