Shared Library Help

Hello everyone,

            I have searched the web for a "Shared Library" tutorial for quite some time and have not found any very detailed ones. Maybe I have missed some good tutorials and therefore I turned to Kirupa. I would appreciate any materials and tutorials that would cover the whole thing. Many tutorials explain either the preloader or the sharing process itself. I am interestend in the whole package. At flashkit they have a nice tutorial http://www.flashkit.com/tutorials/Tips_And_Techniques/Preloadi-mcBassTN-697/more5.php , but it doesn't cover the actual preloader ( where to place it and how). Anyways, I am opened to any resources. Thank you very much!!!! :)
