The exhaustive Grand Canyon–Lower Colorado River regional bibliog­raphy is an ongoing work begun by the author in 1974; pub­lished in print in 1981; and in print, on microfiche and digital disk in 1990 and 1993. An online searchable database superseded the print editions in 2000 and was frequently updated through 2015. The online database included for the first time individual Item Numbers for every item cited. (The online database was removed in October 2021 due to technological issues with its customized software.)

THE GRAND CANON is an emended and greatly enhanced outgrowth of the earlier publications, restoring the monographic presentation of the print editions although now in PDF format. The first edition appeared in 2012. Each edition is cumulative, superseding previous editions although front matter varies.  All editions — 2012, 2015, 2019, 2022 — can be downloaded through the Raven’s Perch Media homepage.

Beginning in 2022 THE GRAND CANON is presented in three volumes.  Volume 1 is the Introduction and Bibliography; Volume 2 is a Cartobibliography; and Volume 3 is the nomenclatural compendium, Grand Canyon: Colossal Mirror.

Users interested in more detailed statistics for the content of THE GRAND CANON (4th Edition, 2022) click on the button below. This is an Excel (.xlsx) file with two spreadsheets. A full-width presentation of the spreadsheets are most conveniently viewed on a ca. 23-inch (diagonal) screen at 64% and 69%, as indicated on the sheets.

Two spreadsheets are provided in this file:

1 ) the yearly breakdown of the number of citation numbers assigned in each part of the bibliography beginning in 2000 (when the Item numbers were created).  The bibliography now on this website lists 106,000 citations in 114 languages (including English), of which about 1,000 are replicated in more than one part of the bibliography due to multiple subject matter). This spreadsheet also includes legacy data for the earlier editions of the bibliography.

2 ) the distribution in each part of the bibliography of all non-English publications (now listing 113 non-English languages, including Indigenous and auxiliary languages).

Each spreadsheet also includes percentage distributions of these data.
