The Mudd Library just subscribed to the New Palgrave Dictionary of Economics, a very useful resource for students and faculty. The dictionary contains readable, comprehensive and up-to-date articles on topics from all fields in Economics. The dictionary is catalogued in LUCIA, and it is directly accessible here (probably only on campus).
I recently found the article on “unforeseen contingencies” very useful–non-technical, yet conveying the important points. The 10 most accessed articles include “liquidity trap,” “Wal-Mart, economics of,” and “financial structure and economic development.”
