Miscellaneous References and Mentions

While our initial information about Spa came from various goverment sources (GNIS), we also found mention of Spa in various books and other sources.

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

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