Warhammer 40,000: Librarium

for the avid collector that collects a copy of every codex, even though they dont play all of them:

also sounds like they redid the unit pages in each of these versions of the codices to match how the new ork one was done. instead of the description page with partial rules, then another page in army lists with everything else, now its all on one page in the description page section, with a picture of the actual model so you know what your looking at. good way to quick reference everything so you can pass your book over to someone not familiar with that army.
