As a developer, I make regualr use of the clipboard, but by itself, it is quite limiting in that it only holds one thing at a time. The moment you copy something else, whatever was there before it overwritten. ClipCache is a potential alternative to this. From their website:

Never lose another address, phone number or other important bit of data again! This powerful, easy-to-use clipboard enhancement tool sits quietly in the system tray monitoring all clipboard activity. Text can be instantly edited on the spot using any of the many handy cleanup functions available, such as removal of the annoying “>>>>>” from emails which have been forwarded too many times, removal of large gaps and white space from emails or web table pasteups, removal of linebreaks and dozens of other marvelous features.

It allows you to store a library of clips, then simply click on a clip and Paste as normal. The program is $20 to register. Check it out at http://www.rosecitysoftware.com/clipcache/.
