Very helpful Morton! Keep them coming!
In the New England area, local lumber companies typically use the “Brosco book” to help contractors pick out and order materials. Here’s an online version of that book. http://www.broscobookofdesigns.com/bod/bookofdesigns2014#pg1
Also, these are some popular brands:
