How can I cite information gleaned from an analysis of newspaper classified ads?

I have to do a project in which I must get some of my information from local newspaper classified ads. I have not been able to find any information on how to handle this in the APA referencing system. Do I have to cite each ad, or can I cite the classifieds from a particular date? What if I use searchable online classifieds? Is there a way to incorporate search terms into a reference?



I would be deeply grateful for any guidance!How can I cite information gleaned from an analysis of newspaper classified ads?I'm sure you can use online classified sites. Try http://www.chowcow.com - I would imagine that you would have to cite each of your references.
