If you are just interested in getting the latest version of a given script these old versions and multiple sites make it harder to tell if the page you have found contains the latest version of the script. To resolve this the below list will take you to the latest version of each particular script regardless of where that latest version can be found.
Note that where a script might be called something different in different places I have attempted to include links under both names. There are also instances where I originally wrote two separate scripts and then later updated one of the scripts so that it now handles what the other did as well. In both these instances you will find multiple links below to what is now one script.
