Referencing multiple BBC news articles

My essay I'm doing has multiple BBC News articles referenced probably about 20 some of which are from the same year.

I know how to reference BBC in the bibliography:

e.g
BBC News (2008) Factory Gloom worst since 1980 [Online]. Available from: http://news.bbc.co.uk/1/hi/business/7681569.stm [Accessed: 21 October 2008]

However say I had another five articles from this year and I wanted to reference them within the body of the essay would I reference as:

blah blah blah (BBC News 2008a) b - c - d etc?

Also how would I make this work in the alphabetical bibliography?

Would I list the references in alphabetical order using the title of the article?

Hope that all makes sense because its confusing the hell out of me!

Cheers
