Q. "Taylor & Francis Online" is requiring me to purchase desired articles

We only have free online access to the 2009-2011 issues; all other articles will have to be paid for.  We do have hard copies of issues from 2005-2011 here in the library, so if the articles you need are from those years you can come in to see and copy them.  You could also try doing searches at http://scholar.google.com, using the titles of your articles in quotes.  Sometimes articles that are otherwise unavailable can be found there.
