Print all 5 pages. Cut the signs. Stick them up. Your space is now addressed.
No rule can make the system more complicated than no system at all.
Start with one shelf. One label. One address. The rest follows.

What is the building or area you're organizing? Choose a 2-letter code that makes sense to you. Common ones are on the reference card. Or make your own — first letter of each word works well.
Cut out the N, S, E, W signs from Page 1. Tape them to the corresponding walls in your space. This is your anchor system. Every address in this space will reference these walls.
Divide your space into areas. Each area gets a 2-letter zone code. Post the zone sign from Page 2 in that area, or write your own on a piece of paper.
Standing at the anchor wall (say, North), number shelf columns left to right: N1, N2, N3. Do this for each wall you use. Now every position in the room has a unique address.
Add the shelf level: T (top), M (middle), B (bottom), F (floor). Then name your items noun-first on the Avery labels from Page 4. Stick them on.
