It's not focused primarily on the collection side, but since I have been in close contact with Bill Webb about Necromancer Games's upcoming release of the Compiled Tome of Horrors, I figured that some of the behind-the-scenes thinking might be of interest. I'm putting up what's probably going to be a two or three part discussion about the decision-making that went into it (mainly with respect to the Swords & Wizardry version) on my blog.
Since I'm not sure when the second part of the article will get posted, you can follow the general blog title at

(It's cooler if you hit the button to "follow" the blog, of course, since it assists my plan to become an evil genius and eventually take over the world)
