I often copy stuff from Autosport because the links go dead after some weeks. But I try to bring the original quotations only and leave the redacting part out. That way you catch the important stuff without abusing the copy right. Typically other internet sites do it in a very similar form and indicate where the interview originally appeared first. So far I have not had any complaints. I would be careful if you copy stuff from Pitpass. They are real sissies with their content protection. Again I would quote just important sentences of interviewees or core statements of the article. Best practice in their case would be posting only links.
Formula One's fundamental ethos is about success coming to those with the most ingenious engineering and best .............................. organization, not to those with the biggest budget. (Dave Richards)
