Jeremy Pierce has a fantastic post on forthcoming commentaries. This details who is down to write missing or replacement volumes for a large number of excellent commentary series. It has also been slowly developing into the authoratitive resource on forthcoming commentaries as various people have posted ammendments and additions to his list. A word of warning though – reading it does feel a bit like sneaking a look at your Christmas presents before the big day arrives, and some of the volumes listed could be many years before publishing (so don’t get too excited).
While you’re over at his site, check out the first of his in depth looks at the commentaries available for individual books – Zephaniah. I’m looking forward to reading more of these in the coming months.
