You get two Serial Numbers so it looks like you can install iWork on two computers. You can register right after putting the in the Serial number which is done when you first start up one of the programs. You also get 4 software coupons with the following saying, "To get software updates and other special offers from Apple, you'll need the coupons below as proof of your purchase." Also, two quick reference guides for all the different keyboard shortcuts for each program. Each with 4 tiles of front and back information. Two user guides with Pages being 191 pages long, and Keynote being 151 pages long. Both manuals are about 5" by 6". Both Apps are fast on my old laptop. See below.
