To Mark & others interested in MEDLINE As mentioned already in this mailing list a program called GREATFUL MED is available from NTIS. This program will allow one to access the National Library of Medicine. Of course you must have an account, but I find the charges very inexpensive. I retrieve all new PD related journal abstracts each month at an average cost of $5.00 per month for about 65 citations. If you also apply for a document account at your nearest medical document library, you can order the full text article thru GREATFUL MED. the add-on software is called LONESOME DOC (included with GREATFUL MED). I haven't used this feature, so I don't know about the cost. If anyone wants the abstracts I have, they are available for the cost of a phone call to my Young Parkinson BBS (805 934-4950, up to 14400 baud, 8N1). The files are in ZIP format for DOS machines. There are over 2 years worth online, one file per month. I also have all PD abstracts going back to 1969 (15 Megs) Greg Johnson [log in to unmask]
