Hi All,
Thank you very much for the many helpful replies. Sorry - I got busy at work and wasn't here as much as I expected to be.
Ed Walsh - I actually do have the free version of Logos - I just don't use it. I think part of it is that, without much of a library, I don't know that the software is all that useful. And, it's hard to justify buying a library for software I don't use. I realize I may use it a ton if I had a halfway decent library, but I really love physical books and am hesitant to buy them electronically for comparable prices, especially for ones I own.
Fred Greco - I completely agree on Monergism.com. I've found some real gems there as far as sermon series go, and the rest of the site is great for other reasons. For Malachi, with something like ten series by names I didn't recognize, I was hoping for a bit of help to narrow it down.
Py3ek - Thanks for the recommendation - I'll try it.
Ian Duguid. Thanks for pointing me to your sermons. I'm downloading them now. I really appreciated your Daniel commentary when I read it a few years ago, and I know my pastor relied on it heavily when he preached through Daniel a bit after that.
