It is exactly the same list as for the 360 version, with a little twist.
To finish LA Noire for 100% you need at least:
26 story cases finished (the DLC cases in this version count too this time!)
40 street crimes solved
30 landmarks discovered
50 film reels collected
8 novels collected (NEW!)
20 records collected (NEW!)
95 cars found and entered
13 newspapers read
The novels and records are new and additional items to collect for the game. They are very easy to find with all of the available guides. I think I finished finding both in under an hour.
Finding both will also award you 100 gamerscore in total, both counting 3% towards the 100%.
Searching for the 20 shields is NOT required for the 100% !
Finding all of the outfits for the game is also NOT required, as the game has 4 new suits with perks.
