It's common (much more than 50% for academic ones, IMHO) that sold articles are freely available on-line. For example, a PDF file of the paper "End-to-end arguments in system design" can be purchased for $15 from: http://doi.ieeecomputersociety.org/10.1145/357401.357402 which is the first link appears in google scholar search with the paper title, or, from: http://portal.acm.org/citation.cfm?doid=357401.357402 to which the above IEEE link is redirected, but is available free of charge from: http://web.mit.edu/Saltzer/www/publications/endtoend/endtoend.pdf which is the second link (next to google scholar one) with plain google search. It is a lot more time (and money) saving to search free versions before entering transactions to purchase them than to rely blindly on PubMed, IEEE, ACM, google scholar etc. Masataka Ohta _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
