Narrative:

Once cleared for the crazi one arrival into bil; I looked down to locate my northwest vol 1 of the FAA us terminals procedures publication. Upon opening the publication to section 'Z' arrivals; I was unable to easily find the crazi one arrival. I expected the arrivals to be grouped by the arrival airport; but they were not. They appeared to be in no logical order. During the time it took me to locate the procedures; as I missed it on the first pass; I became spatially disorientated and lost what I initially read was three hundred feet on the altimeter. When ATC reported radar contact lost and questioned me on my altitude I reported what I was seeing as 16.7. Once I looked outside and was able to reorient myself I realized I was closer to 1500 feet low.when flying [single pilot IFR]; the easier it is to locate procedures the safer our life will be. I am sure this is not the first time something like this has happened. A simple change of placing the arrivals in alphabetical order under the appropriate airports along with the departures would help minimize the potential loss of life.
