Some of the ruleset PDFs on this wiki are formatted as pocketmods.
Pocketmods are a nifty, no-staple, origami-like way to make small booklets. For instance, there's a pocketmod chapbook containing an excellent science fiction story called "Printcrime" by Cory Doctorow that may have some relevance for piecepackers.
PocketMod.com has an application that lets you turn any PDF of eight pages or fewer into a PocketMod. Here are some piecepack pocketmods. They're surprisingly readable, even without tweaking font sizes. Printing them in color makes them more so.
