Miscellaneous References and Mentions

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

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