Here are several excellent sources of rabies information online.
For the Department of Agriculture website where you can download information about rabies in Pennsylvania or the Rabies Submission Form for Nonhuman Exposure submissions for the Department of Agriculture laboratory.
For the Pennsylvania Department of Health website where you can download the Human Exposure Form. http://www.portal.state.pa.us/portal/server.pt?in_hi_space=NetworkSearch&in_hi_control=NetworkSearch&in_hi_results=true&in_su_b1=Search&in_tx_query=rabies&in_se_numresults=5&in_cb_savelocations=true&in_cb_source=-2&in_cb_source=200
For the Compendium for Rabies Control from the National Association of State Public Health Veterinarians and other rabies information:

For the Rabies Law in Pennsylvania, you can find that on the Pennsylvania Code website: http://www.pacode.com/secure/data/007/chapter16/chap16toc.html
I have also attached a pdf version of the Rabies Law.
