Looked and looked again, found his books but not him, went on from their. I saved the game at that point, in case I decide to look for him again, which I may use the cheat console. But I went on and started another saved game and ended up in the morgue, where I did not find the key to the second floor door. Got into the third floor door, and the first door in the fourth floor but cannot get into the library, I guessing that is what that door leads to. I read some threads with the same issue, but never clear if they solved the issue. One thread in particular where they humiliated the guy to the point that he finally said he got in but did not say if even found this morgue key. I am thinking he must of and just did not say where or how. In my case, maybe the key fell into the wall space or sewer space where I cannot dwell. I don't know.
