After 10 years doing physics research at Bell Labs, Eric got interested in electronic publishing, started an e-journal, started a company, built linking technology for libraries, sold that company to OCLC and worked there a few years, started blogging, and finally decided that the important thing to do would be to make e-books work for libraries. And everyone else. But the legacy of working on scholarly citation software made him swear long ago that his author-string would be E.S. Hellman, so don't get it wrong. He lives and works in Montclair, New Jersey.
