I recently started my PhD program and have already accumulated a vast amount of papers on my to-read-list. I never had troubles reading and remembering content of academic papers, but this pile is giving me headaches. So much so, that the comment and note functions of my reference management software (Zotero) does not seem to be sufficient to keep track of all the information.
Previous attempts to structure key findings in all this literature have resulted in fragmented lists that just add on to my confusion. I also tried mind mapping applications but feel like there must be some kind of best practice on how researchers structure and extract information on a larger scale (~150 papers).
EDIT: My goal is to quickly gain an extensive overview of my current field of research and its neighboring constructs, including unanswered or potential research questions, hypotheses that were previously investigated. What tools are commonly used beyond reference management software?
I'm aware that this questions has no objective true answer, but find it nonetheless important. Thank you!
