Given taxi instructions onto inactive runway to wait for center release time. Aircraft was on taxiway O at switch from ramp control to ground control. Pit ground instructed us to taxi via P to runway 32L, on 32 hold short of G. No problem with taxiway P and runway 32 as both captain and I had been based at this aerodrome for several yrs. Upon turning left (southeast) on runway 32 I asked the captain if he had any idea where G was. He replied that he had no idea, but would continue taxiing on runway 32 until he saw a sign. I told him that I'd have a look at the airfield diagram. He replied, 'don't bother with that,' and continued taxiing. While I was heads down digging out and figuring out the airport diagram, we taxied past G, across runway 28C (an active runway) and stopped short of C on runway 32. Visibility was excellent and captain could see that there would be no conflict crossing runway 28C, however we were not cleared to do so. Ground instructed us to hold short of C on runway 32 to await our release time and then had us taxi back for takeoff on runway 28C. He informed us of our error, which I had made the captain aware of shortly after we stopped at C. Factors: captain continued to taxi, when unclr of route. Complete lack of signs or other guidance on aerodrome. No sign at taxiway G or C visible from runway 32 taxiing sebnd. First officer should have had airport diagram page open and available, but did not due to familiarity and usual routine at home drome.

Title: ACR MLG UNAUTH TAXI/UNAUTH RWY CROSSING.
Narrative: GIVEN TAXI INSTRUCTIONS ONTO INACTIVE RWY TO WAIT FOR CENTER RELEASE TIME. ACFT WAS ON TXWY O AT SWITCH FROM RAMP CTL TO GND CTL. PIT GND INSTRUCTED US TO TAXI VIA P TO RWY 32L, ON 32 HOLD SHORT OF G. NO PROB WITH TXWY P AND RWY 32 AS BOTH CAPT AND I HAD BEEN BASED AT THIS AERODROME FOR SEVERAL YRS. UPON TURNING LEFT (SE) ON RWY 32 I ASKED THE CAPT IF HE HAD ANY IDEA WHERE G WAS. HE REPLIED THAT HE HAD NO IDEA, BUT WOULD CONTINUE TAXIING ON RWY 32 UNTIL HE SAW A SIGN. I TOLD HIM THAT I'D HAVE A LOOK AT THE AIRFIELD DIAGRAM. HE REPLIED, 'DON'T BOTHER WITH THAT,' AND CONTINUED TAXIING. WHILE I WAS HEADS DOWN DIGGING OUT AND FIGURING OUT THE ARPT DIAGRAM, WE TAXIED PAST G, ACROSS RWY 28C (AN ACTIVE RWY) AND STOPPED SHORT OF C ON RWY 32. VIS WAS EXCELLENT AND CAPT COULD SEE THAT THERE WOULD BE NO CONFLICT XING RWY 28C, HOWEVER WE WERE NOT CLRED TO DO SO. GND INSTRUCTED US TO HOLD SHORT OF C ON RWY 32 TO AWAIT OUR RELEASE TIME AND THEN HAD US TAXI BACK FOR TKOF ON RWY 28C. HE INFORMED US OF OUR ERROR, WHICH I HAD MADE THE CAPT AWARE OF SHORTLY AFTER WE STOPPED AT C. FACTORS: CAPT CONTINUED TO TAXI, WHEN UNCLR OF ROUTE. COMPLETE LACK OF SIGNS OR OTHER GUIDANCE ON AERODROME. NO SIGN AT TXWY G OR C VISIBLE FROM RWY 32 TAXIING SEBND. F/O SHOULD HAVE HAD ARPT DIAGRAM PAGE OPEN AND AVAILABLE, BUT DID NOT DUE TO FAMILIARITY AND USUAL ROUTINE AT HOME DROME.
