I want to start an article website that's really contructive, easy to use and provides interesting and up to

date articles on various subjects. I sometimes find good health articles in mags like Cosmo or Glamour and feel that many people might miss out on this info because they dont read these mags. Would I have to ask the author's or the magazines that published the article for permission. I was thinking of including the author's name, the magazine it came from, issue number and date. Also a link to the magazines website if possible. Do you think this would be a good idea and how would I go about doing this? There dont seem to be good organized article sites out there.
