Need suggestions on how to keep track of blog posts/URL's for future reference

Tweet

I use BLogger and like it. I have several blogs and a couple other sites where I write. I want to make a spread sheet or something like that where I can type out the names and URLS of all the posts I make, the URL's to the articles I write, etc so that I can reference between them and cross post similar things. Right now, I just have them listed on a sheet of paper (typed so I can copy and paste) but keeping them in order as to topic so it is easier to find is a problem. Question:.. Any suggestions on how to keep track of all the posts/articles I write and keep track of the titles and URL's the easiest way so that I can reference them quickly and often? How do you do it?
