PHYSICIANS' DESK REFERENCE The PDR internet site requires registration, using your DEA and SS numbers. In addition to full text PDR, this site also offers free MEDLINE searching.
PHYSICIANS' ONLINE (POL) is a proprietary service not on the internet and available only to practicing physicians (MD's and DO's; requires DEA and SS numbers to register). POL, funded by corporate sponsors, offers free e-mail, plus MEDLINE and numerous other medical information services. Provides internet access for a fee. Of note, POL lists practically all medical sites on the internet, and ranks them (based on physician surveys) from 1 (lowest) to 5 (highest). Software can be ordered directly from the POL web site or by calling 1-800-332-0009.
