Last Chance to Read?

So I noticed when going on the Website version of DC Universe that the Grant Morrison run of “Animal Man” was under “Last chance to read” and it kind of surprised me. DC is saying they’re dedicated this month to putting on the entirety of the Digital Library minus the last 12 months, and to be honest have done a Herculean job of it so far! Still, are they still going to pull titles here and there? Why?

Basically DCU in return for the ultimate library, is giving up vertigo to Comixology.
