This blog is possible only because of the work of librarians from many institutions. The librarians at Waidner-Spahr Library (Carlisle, Pennsylvania) continue to be especially helpful. Other particularly valuable library resources include:
Biodiversity Heritage Library
California Digital Newspaper Collection
HathiTrust Digital Library
Searchable Ornithological Research Archive
I also offer appreciation to those who trade in old books, magazines, artifacts, etc. These dealers help to make sure that these materials are not lost and forgotten.
I am grateful to the thousands of people who have worked and are working to insure that California condors are alive today and flying free. Many of these dedicated individuals are employed by federal and state government agencies, including:
Arizona Game and Fish Department
Bureau of Land Management
California Department of Fish and Wildlife
Fish and Wildlife Service
National Park Service
Still more individuals are employed by non-governmental organizations that are funded by charitable contributions. Please support these, including:
Los Angeles Zoo
San Diego Zoo
Santa Barbara Zoo
Ventana Wildlife Society
Zotero freeware, developed and supported by the Corporation for Digital Scholarship, helps me maintain the bibliography that is the foundation of this blog.
The California condor logo image was custom designed for this blog by artists Rosa Chung and Chris Law.
