This month's
free Logos book is a volume from another well-respected, scholarly series. From
The New International Geek Testament Commentary, the volume on Mark is free, the combined Colossians and Philemon volume is $4.99, and 1 Corinthians is $9.99.
The commentaries are critical, theological, and exegetical. Since they focus specifically on the Greek texts, they have much more critical information (discussing textual variants and probable original readings) than most other commentaries.
The books can be read in the
free Logos software or
online.
Keep in mind that we're near the end of the month, so there will be a new book next week.
There are also monthly free books for the same software at
Verbum (the Catholic version of Logos) and
Faithlife (for more popular works, rather than academic).
