THE RAVEN'S PERCH MEDIA WEBSITE DISPLAYS FLUIDLY ON DIFFERENT DEVICES — APPEARANCES WILL VARY.  DESKTOP SCREENS ARE RECOMMENDED DUE TO DOCUMENT SIZES AND PRESENTATION FORMATS.

NO REGISTRATIONS OR LOG-INS ARE REQUIRED.  NO INFORMATION IS ASKED FOR.  NO WEB COOKIES ARE TRANSFERRED BY RAVEN'S PERCH MEDIA TO THE USER'S DEVICE.

ALL PUBLICATIONS HAVE BEEN WRITTEN AND PRODUCED WITHOUT THE AID OF ARTIFICIAL INTELLIGENCE OR GENERATIVE LANGUAGE MODELS.  NO HISTORICAL OR COLLECTIVE CENSORSHIP IS EXERCISED.

USEFUL FINE PRINT :

MOST ITEMS IN THE LIBRARY ARE DOWNLOADABLE SEARCHABLE PDFs.  File size in megabytes (MB) and number of pages are indicated on each download button.

MANY OF THE PDFs EMBED ACTIVE HYPERLINKS that allow users the option to navigate to other places within the publication or to external websites.

MOST PDFs ARE DESIGNED IN BOOK LAYOUT for opposing-page viewing on wide screens, but viewing as sequential pages is satisfactory.

NEARLY ALL PUBLICATIONS ARE ALSO AVAILABLE AS ONLINE FLIP BOOKS — LINKS ARE PROVIDED ALONGSIDE THE PDF DOWNLOAD BUTTONS.  Flip book are offered as a convenience for some users, who may not need or are unable to download PDFs. The flip books cannot be downloaded but are fully searchable. Within flip books, embedded hyperlinks are all active. The URLs for the flip books can be copied and shared. Limited page saving and sharing from the flip books may be possible.  URLs for flip books may be transient; they are not hosted by Raven's Perch Media.

IN NOVEMBER 2025 THE MOST CURRENT EDITIONS OF RAVEN'S PERCH PUBLICATIONS WERE ARCHIVED VIA THE “INTERNET ARCHIVE” ONLINE (https://archive.org), posted there with "Creative Commons" licenses. Initial displays are like flip books; from those web pages the PDF can also be downloaded. To locate all Raven’s Perch publications archived on the Internet Archive use the “Search metadata” field there and type in (with quotes) “Raven’s Perch Media”, which will display a unique list.

THE SEPARATELY AVAILABLE PUBLICATIONS LIST (also a website tab) is a transportable PDF. Containing descriptions of all publications, it is updated when new publications are added. Each publication in the list has a direct download link, some with additional format links (see above).

URLs for Raven's Perch Media publications are persistent for as long as the host of the Raven's Perch Media website exists.  Users are encouraged to download PDFs to incorporate into digital libraries.  See the REPRODUCTION AND FAIR USE STATEMENT on the Copyright Page of this website. Most publications also contain the Reproduction and Fair Use statement.

SPECIAL BIOLOGICAL BIBLIOGRAPHIES

This section of the website contains separate bibliographies for specific groups of biological taxa, relating chiefly to the Grand Canyon region.

OTHER SPECIAL BIBLIOGRAPHIES AND HISTORICAL VOLUMES
