Obverse Books has begun a series of critical Doctor Who titles under the banner of Black Archive. This looks like a series that will take its time as it intends to cover each story in a separate book, six titles a year, each of 20,000 – 40,000 words.
Basic arithmetic suggests it will never catch up as long as there are (on average) just over six episodes a year but that’s arithmetic for you!
More interesting is the fact they are holding open submissions throughout 2017, something I will be considering seriously. Details are here: 2017 Submissions.
