According to my own detailed searches over the past few years, PEBL has now been cited or used by over 100 articles, theses, and tech reports. A detailed list, with links, is located at http://pebl.sourceforge.net/wiki/index.php/Publications_citing_PEBL#Theses_and_Technical_Reports
If you have published a paper using PEBL or the PEBL Test battery, please check to see if you are listed. If not, let us know. And if you are in the process of publishing, be sure to cite PEBL!
