SUPPLEMENT AND STATISTICS CURRENT TO 20 AUGUST 2020

©2020 Earle E Spamer


The Supplement contains citations of new and old publications gathered since the January 2019 release of the 3rd Edition of THE GRAND CANON. The content of this Supplement is incorporated in the 4th Edition now in preparation; however, at this time no date of completion of the 4th Edition is projected.

The Supplement contains approximately 9,000 new citations. Signifi­cant emenda­tions to pre­viously published cita­tions are also listed here; each is noted by a special symbol. Routine correction of typographical errors that do not change important bibliographical information, which have been made to the 4th Edition in preparation, are not included in the Supplement.

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 An online searchable database superseded the print editions in 2000 and was frequently updated through 2015.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 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 — can be downloaded through the Raven’s Perch Media homepage.


STATISTICS

Users interested in basic statistics that relate to the content of THE GRAND CANON may click on the button below. This is an Excel (.xlsx) file with two spreadsheets. A full-width presentation of each spreadsheet is most conveniently viewed on a ca. 23-inch (diagonal) screen at about 67-70%.

These statistics are the current data for the 4th Edition now in progress, which include the citations from the 3rd Edition of THE GRAND CANON plus the Supplement that is posted to this page (above).

Two spreadsheets are provided in this file:

1 ) the yearly breakdown of the number of citations in each part of the bibliography from 2000 (when Item numbers were created) to the present (now listing 100,000 citations of which up to 1,000 are considered to be replicated in more than one part of the bibliography due to multiple subjects)

and

2 ) the distribution in each part of the bibliography of all non-English publications (now listing 109 foreign, Indigenous, and auxiliary languages)

Each spreadsheet also includes percentage distributions of these data.
