Spoilers are strongly policed here.
If this thread's title doesn't specify it's spoilery, don't bring any up.

This page lists appearances of K9 Mark II in the order in which he experienced them. This timeline is based on observations of the Doctor Who universe and the events in each of these stories. From these observations we have attempted to build a concise timeline. It is assumed, much like their TV story counterparts, that each novel or audio series their published/numbered order is the order they occur in.

The layout of this timeline is based in part on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, Lance Parkin's AHistory and other sources that allow us to make observations, such as DocOhoReviews, The History of the Doctor, The Discontinuity Guide, Clive Banks Databank, the Big Finish forums and The Divergent Universe forums. None of these sources should be used solely as a source or considered a "true" timeline for stories.
