Dog novel & research has slowed to a crawl

I've reached journal #10 for the dog gangster story, writing time (which usually ran 3-5 pages a day) has slowed.
Also, researching has changed. I did commando-style skimming, flipping through certain chapters, trying to finish other chapters on a given topic.

Now, I do a more in-depth research, where I find time to read each reference as a novel.
