Databases to Download

Many of these sites have structured databases that can be downloaded and imported into either a spreadsheet or a database for querying. An Excel file is easily imported into an Access database. I have found, however, that the best results are obtained by first opening the file in Excel, selecting the part that is structured like a database, and copying that to a separate sheet.
