well, there is nobody there to automatically protect your copyright, you must identify infringement and take action.
sometimes people confuse copyright with patent.
copyright refers to the right to publish, perform or record literary (or musical) material and legally authorize others wishing to profit via republishing such work, this does not include profit while using material for news or even lampooning.
patent refers to a governmental authority created to confer legal right to sell or use a specific process or device (something fabricated) to the inventor.
in the case of copyright infringement, you'll have to engage a lawyer, or defend yourself, but there is no way to provide any sort of automated protection on your behalf.
you can look up stuff about copyright defense, but basically you can pay a small fee to list your work as "copyrighted" and this could certainly be used to support any claims of ownership.
It is certainly possible to copyright software code, print out just the first 50 pages or so, and submit here:

Even still, it is you who must be active against infringement by taking legal action. Typically, this starts with a lawyer's letter demanding cease and desist for republishing unauthorized copyrighted literature.
Hope that helps
