Miscellaneous References and Mentions

While our initial information about Sodium came from various goverment sources (GNIS, FIPS), we also found mention of Sodium 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 Sodium. We hope that they will be useful to you.

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