And go the the college library for the (expensive for them-most likely free for you) database access. Here is a sample cost for a very large University:
In 2005-2006

Current Serials (ongoing) – $6,629,327
Electronic serials – $2,836,208

Word is in Library school right now there appears to be a trend. Because larger schools are charged more for their database subscriptions, smaller schools get more for less and sometimes even have more databases. However most any college library will do, consider the reality that large schools have had to drop key databases to save money.

The point is go use those databases they are excellent. Yesterday I had the happy experience of finding an awesome NPR radio show I had heard a while ago via Lexis Nexis, it was so simple once I knew to go there, I could text search the transcript, so all I needed was a rough time frame of when I first heard it (the past few months) and some meta. Has that ever happened to you where you are listening to a talk show on the car radio and months later you really want to hear that show, well it is not so hard to find it as you might think with Lexis Nexis.
