Export the project as a Library (File -> Export, it's an option there)
Then import that to the new Library.
However, as an Aperture Library can manage up to 1,000,000 photos, why would you break up libraries by year? I know folks did this with iPhoto (prior to iPhoto 6) when those libraries could manage only 25k, but it make little sense when you can have all your photos in one Library, and devide them by year too, in that Library.

Thanks for the help.
I am thinking of moving the older library to an external hard drive and just keeping my current library on my internal HD. I was also under the impression that Aperture would run a little faster with a smaller library--is that not the case?

The size of the library is not critical for the overall performance. You may notice a little reduce in speed, if the projects are gigantic. I would not put thousands of images into one single project.
But it is more important to keep plenty of free disk space on your system drive, and to have the Aperture library on a fast drive with a fast connection. Also fix your Aperture library by repairing it, if you had a crash or you force quit Aperture.
If Aperture is slow, try to find out, what it is doing by looking at the Activity window (Window > Show Activity). There you can see, if Aperture is processing previews, scanning for faces, etc. Sometimes Aperture is processing the same image over and over again. If you see this happen, remove the the image from the library. Probably it is corrupted.
