Miscellaneous References and Mentions

We've created the following list to keep track of the sources that proved useful in adding to our knowledge about Duquesne. We hope that they will be useful to you.

Note: When we started collecting data about Duquesne, we were inconsistent about keeping track of where that data came from. As a result, this list of references and mentions is probably incomplete.
