You get monologues from plays, for the most part. Find a play you would like to be in, pick the character you like, and find a bit where the character is talking for a minute or two at a time. (or however long you need your monologue) You can simply find plays in a library or bookstore.
You are invited to take a look @ MonologueBlogger.com, "The Actors Free Monologue Service Provider".

Good monolog sites are the ones you can see on television. The major networks have late night television shows. Each of these talk shows starts off with the hosts doing a monolog.
No a monologue is a noun because it is a thing. If it was a verb then you could say this correctly. Yesterday I monologued. This doesn't make sense. Hope I helped!
