Are DC and Marvel retreating from the book and library market?

This post at Comics Beat talks about how, in the year since Disney bought Marvel and DC announced changes in management, they haven't really made any real achievements; surprise, surprise. But what raised my eyebrows was the following:

Neither company seemed to do much in the bookstore or library markets. They actually seemed to be retreating from these markets. Neither company exhibited at BEA or ALA. DC was marginally represented by Random House at these shows; only a few of their books were on display at ALA and Random House had a greatly reduced presence at BEA. At the very least both companies should have a least one staffer around to answer questions. I only saw one DC executive at BEA and didn’t see anyone from Marvel. Compare this to the army of people they send to San Diego Comic-Con.

No talent from Marvel or DC toured bookstores or libraries and I didn’t see any significant expansion of either publisher’s books on the shelves.

No kidding. And they wonder why they're fading away. Truly, they want to fail. That's why we can't even expect them to change their marketing approach and switch from pamphlets to a more viable format.
