I love PDF documents, but I don’t often find the need to actually create one. A few months ago, I found that Adobe has a service called Create Adobe PDF Online, where for $9.95 a month you can create unlimited numbers of PDF documents. Not bad, but I don’t want to spend ten bucks a month if I only need one or two PDF documents every other month. A new product was introduced recently by the National Library of Medicine called DocMorph, which apparently converts documents to PDF for free. I haven’t tried it out yet, but I plan to soon.
