The information on this page has been gathered over a period of 10+ years, and its applications are not limited to the region of Northeastern Pennsylvania (USA). The order that the material is presented in may
appear out of sequence, since it is taken quickly from a website first posted here a decade ago but which now appears dated. This does not diminish the value of the material, however. Additional material will also appear in the near future. Also, please be kind and report broken links.
