Arkansas - Any Recommendations for Good Guides, Maps, Hikes?

[Driver8]

I'm headed home to Arkansas for Thanksgiving, my first trip there since I got heavily into hiking. Hope to hike at least one nice peak on the visit, which will be brief, giving a two-day window for hikes. I've done some looking online, and the Arkansas state park websites for Nebo and Magazine have only cursory information. Can anyone recommend a better source? As for guidebooks, it's a bit late for me - I might just have to pick up a book once I get home.

Also, anyone who's hiked Arkansas, please chime in with recommendations. Most likely, I will do Mt. Nebo, which I am sure will live up to its rep for great views. But my ears are open to recommendations. I've hike Petit Jean State Park, Pinnacle Mountain and Lake Fort Smith, western Ozark Highlands trail stretch. That's about it. Thanks in advance.
