This project grew out of my son Joshua’s stated desire to read the entire run of the authorized Tarzan novels - the original series by Edgar Rice Burroughs, and those ERB Inc.-sanctioned novels by Fritz Leiber, Philip José Farmer, Joe Lansdale, Will Murray and Michael S. Sanford - more or less in the order in which they take place. When Josh announced his intent, I decided to compile this chronology for the purpose of helping him and other fans who might be considering a similar reading project. (It was not my first such project, having previously compiled for my father a similar chronology for reading the two different Han Solo trilogies by Brian Daley and A.C. Crispen.)

Determining such a chronological listing can present something of a problem for those who are fans of Farmer’s “Wold Newton” mythos. In his biography of the character, Tarzan Alive (in which Burroughs’ original novels are depicted as being a fictionalized account of an actual person’s life), Farmer asserts that some of the original novels were published in a different order than in which the events they described actually transpired. Though a fan of Farmer’s Wold Newton works, for the purpose of this particular exercise Joshua opted to read the original ERB novels in the traditional sequential order assigned by Ballantine Books - with the exception of Volume 6, the short story collection Jungle Tales of Tarzan, which recounts tales of Tarzan’s youth, and which is included here in the place determined by Farmer in Tarzan Alive.

Chronological placement of the one ERB book not included in the Ballantine reprints, Tarzan And The Tarzan Twins (the combined title under which two shorter works - The Tarzan Twins and Tarzan And The Tarzan Twins With Jad-Bal-Ja The Golden Lion - were published in book form by Canaveral Press in the 1960s), is based on publication dates provided by Richard Lupoff in his study Edgar Rice Burroughs: Master of Adventure. (Similarly, although Tarzan is only a minor character in the book, I have included ERB’s The Eternal Savage based on Lupoff’s discussion of the book.)

Lieber’s Tarzan and the Valley of Gold - a novelization of the 1966 film starring Mike Henry, which Leiber wrote to fit in with the original novels and was published as Volume 25 in the series by Ballantine - clearly takes place during that specific time period. It is obviously set some years after Tarzan: The Lost Adventure - Lansdale’s posthumous collaboration with Burroughs - which takes place following Tarzan’s return to Africa after the conclusion of World War II. Which means that there are more adventures yet to be recorded that fit in the period of time between the semi-cliffhanging ending of The Lost Adventure and the events of Valley of Gold - and that, in turn, means there will surely be future revisions to this chronology. 

Placement of the remaining post-Burroughs titles was, for the most part, easy to deduce from readings of the books themselves. The only one we weren’t entirely sure about was Will Murray’s King Kong vs. Tarzan, and so I went directly to the source; Will was nice enough to respond to my e-mail inquiry on Joshua’s behalf, and thus that book’s placement herein is based on the information provided by Murray.

At the time I started this project, Leiber’s novel was the latest novel in the series chronologically. Since then, ERB Inc. has published Tarzan: The Greystoke Legacy Under Siege by Ralph N. Laughlin and Ann E. Johnson. The bulk of this book takes place in 1985 (the first several chapters take place in 1971), and introduces a new member of Tarzan’s family: Jonathan Clayton, Tarzan’s great-grandson. (It's a pretty good book; read it if you haven't already.) The book offers indications that further adventures set in this time period are forthcoming, and when they are released they will be added to this chronology.

Although I originally did not intend to, I have also included the three authorized Tarzan short stories that appear in the 2013 anthology Worlds of Edgar Rice Burroughs. One of those stories, “Tarzan And The Martian Invaders” by Kevin J. Anderson and Sarah A. Hoyt, depicts Martians more in keeping with the invaders of H.G. Wells’ The War Of The Worlds than with the denizens of Barsoom created by Burroughs in his “John Carter of Mars” series. As a result I nearly opted to exclude this story… until I remembered another short story that appeared in the earlier Anderson-edited anthology War Of The Worlds: Global Dispatches. That story, George Alec Effinger’s “Mars: The Home Front,” demonstrates that Wells’ Martians do indeed exist on Barsoom alongside ERB’s Tharks, and so I changed my mind and included the Anderson-Hoyt tale as well.

One other note: For the purposes of this exercise, “authorized” novels means those books that are obviously connected to the original Tarzan canon as authored by Burroughs. There are other books that have been authorized by ERB Inc. over the years but are obviously NOT canonical, such as R.A. Salvatore’s Tarzan: The Epic Adventures and Jane by Robin Maxwell - both of which are “reimaginings” of the original stories, as opposed to additions to the existing saga. As such they are not included here.

By that same logic, I am also excluding both Thomas Zachek’s Tarzan Trilogy, a collection of three stories set prior to Tarzan’s involvement in World War II; and two novels by Jake Saunders, Tarzan And The Cannibal King and The Martian Legion: In Search Of Xonthron (the latter of which also features ERB’s other great fantasy hero, John Carter of Mars). All three books were authorized by ERB Inc., but they feature depictions of Tarzan and some of his supporting cast which simply are not compatible with the original Burroughs canon. (Nkima was NOT a female.)

Some fans will no doubt object to this, which is of course their right. And I certainly mean no disrespect to either Mr. Zachek or Mr. Saunders, both of whom have told the stories they wished to tell and found an audience receptive to those tales - and as a writer myself, I know how important that latter is. But for me as an individual reader, I simply feel that the discrepancies in depiction on display in these books are just too great to warrant their inclusion as “canonical.” 

And to paraphrase a comment one of the authors made during a panel discussion I attended at the 2017 ECOF (Edgar Rice Burroughs Chain of Friendship) Convention in Irving, Texas: It’s my list, so I can do what I want.
