Haven’t tried it but this free, open-source software called Neuroscholar seems interesting. The idea seems to be to provide an easy tool for collecting and comparing facts and interpretations across different papers. It uses a SQL database backend and some graph-like data representation for the front-end.
I’d be curious to hear about anyone’s experiences using it or any similar tools. I still have yet to find a good way to organize my PDFs…
From the website:
NeuroScholar is an open-source and is free for download from http://www.neuroscholar.org/ (click on Software > NeuroScholar ). We also have several demonstration movies available from the movies section to show the functionality of the system.
