Swartz faced 13 felony charges, including breaching site terms and intending to share downloaded files through peer-to-peer networks, computer fraud, wire fraud, obtaining information from a protected computer, and criminal forfeiture.
He pleaded not guilty to the charges. His federal trial was to begin next month. If convicted, he faced decades in prison and a fortune in fines.
JSTOR announced this week that it would make "more than 4.5 million articles" publicly available for free.
