You have reached a link to the now dicontinured bibliographic reference system which Beyond Intractability used many years ago. Because of funding limits, we were unable to update and maintain this very expensive system.
As part of the transition to BI's new computer system, we are, however, working to update and move over the Essay Additional Reference part of the bibliographic system. Because of differences in the way the two systems are structured, this is a complex and time consuming task which, again because of limited funds, we are undertaking on a time available basis. Current plans call for completing this aspect of the transition during the Spring of 2017.
In the meantime, available bibliographic references can be searched for by using our Search Plus External Links system.
