How are you managing hundreds of papers for your lit review? My system is breaking down

[Maya Reyes]

I'm a third-year PhD student in Information Science, and I am now very busy conducting a systematic literature review. My Zotero has 340+ papers and I genuinely don’t know what agrees and contradicts anymore.
So here's what I'm doing: Zotero storage → PDF annotations → Obsidian notes → copying into a Google Doc to format the argument. It works but it's slow and I keep losing track of which papers say what across different themes.
Just curious to hear what systems other PhD students have come to rely on, particularly as they work on the synthesis stage (not just paper storage, but actually connecting ideas across the whole corpus). What’s working for you?
