Mr. Johnson's Little Black Book (Shadowrun)

I came into Shadowrun in 4th Edition, then 5th, but 6th had me looking for something more my style. A friend suggested trying 3rd edition and I was hooked. This book is a terrific resource for storytellers, giving contact info and ideas for runs.

This is a rather nice collection of game tips, contacts and adventure ideas. Most of the contacts have appeared in SR4.If you want to roll up a block of buildings on the fly, this has tables for you.The adventures ideas could certainly be adapted for SR4.Pretty neat collection.

Definately a GM resource. Lots of information and ideas on how to set up runs, manage contacts, plot adventures, etc. Pretty much zero fluff or setting material (outside the example bits of fiction). If you're an experienced GM, you probably won't need most of what's available, but might be worth a look before you buy.
