A B767-300 First Officer reported that hazmat was improperly loaded on their aircraft and had inaccurate documentation.

Narrative

This is a hazmat loading issue which is becoming more and more frequent here at my air carrier. 30 minutes before push 3 hazmat forms were handed to Captain which he looked at and started to file with the flight papers. I asked to please look at them which I did and then I looked at our dangerous goods section of the manual to see if there were any restrictions. I did this because I have had several problems with loading in the past. I saw that 2 of the 3 packages could not be in contact with each other and advised the Captain. The Captain asked if I would go out on the ramp and ask the baggage folks to verify. I was asked if I wanted to crawl up in the bin and verify with him which I accepted. When in the bin I saw not 3 but 6 hazmat packages thrown in the corner some upside down and all touching each other. I asked why no notification was given of the other 3 with no good answer. I asked to see the papers on the 3 we had no paperwork for and they could only produce 2 forms. I noted that of the 5 I had paperwork on that 4 could not touch each other. I had the 6th package without paperwork removed and asked for assurance that the remaining boxes would have luggage between them. I went back and informed the Captain who called for a Ramp Supervisor and I explained to her what happened. I guess it was taken care of from there. I don't know who filed what but I couldn't let this go unreported. Things like this seem to be happening more and more at my air carrier..
