Parson's Klog entries are a series of articles about Erfworld rules, characters, and important information interspersed among the story of the Battle for Gobwin Knob. The entries are modeled on a Blog one could find on the Internet, so they also include private thoughts, speculation, and ramblings. The Klog itself is written in his Eyebook.
The name "klog" is derived from "eyebook log" in the same way the term "blog" is derived from "web log".
Situation Room Notes
It is unclear whether Parson renamed the Klog, abandoned it, or began a concurrent set of notes, but he has recently made some "situation room notes." Aesthetically, these are the same as the Klog (minus Hamstard) and are almost certainly recorded in the same eyebook.
