This section offers FREE files that you may download.  These are all freeware that I use frequently and have found to be useful.  I have either found these in the public domain on the web, created them myself, or compiled existing data into an electronic format, with credit given within the file to the data's original author (if known).

Spreadsheets for Download

These require Microsoft Excel 98 or later to read.  Alternatively, you can use OpenOffice.org as a very functional, free alternative to Microsoft Excel.  You can use it to exchange files with people running Word and Excel.  It works under Linux and other OS's to give you a way to use Excel spreadsheets.
