grateful to all for their valiant attempts to keep us out of harm’s way. Having said this, we also absolve all of our 
friends of any guilt for the errors we know persist in the work. They are our responsibilty, and we alone bear the 
blame. 
Finally, the authors of this bibliography are listed in the order determined by a “toss of a coin.” Their con¬ 
tributions were equal though they placed emphasis on different areas. Initially, Leviton handled most of the pub¬ 
lications for the 18th and 19th centuries and the geological literature whereas Anderson focused on the 20th cen¬ 
tury as well as regional geography, ecology and ancillary non-herpetological, neontological literature. Nonethe¬ 
less, across the years there was considerable overlap in their activities as well as in the addition of materials for 
the first decade of the 21st century. Both recognize and accept equal responsibility for the strengths and weak¬ 
nesses of this compilation. Furthermore, both are committed to an ongoing effort to upgrade the bibliography, to 
correct known and emergent errors, to expand it as new materials appear in press, and to respond positively to 
our colleagues who, we hope, will take time to bring to our attention errors of commission and/or omission. Up¬ 
dates, including both corrections and additions, will be issued on an irregular basis. Also, to facilitate the work 
of others, we ask our many friends and colleagues, if you find this work useful, to mention it in the acknowl¬ 
edgments and literature-cited sections to encourage wider distribution. And, to repeat what we said a moment 
ago, send us your comments, however complimentary or not, as well as corrections, updates, and additions, all 
of which we will both gratefully acknowledge and incorporate in our planned supplements. In addition to the 
printed version, this bibliography is available online at <www.calacademy.org/research/ scipubs> as a down¬ 
loadable PDF file. 
In closing, we apologize in advance to our colleagues that, much to our regret, we are unable to respond to 
requests for copies of most of the papers in this bibliography inasmuch as few have been scanned and we lack 
the clerical assistance necessary to do more. Furthermore, copyright restrictions prohibit the wholesale copying 
of materials for secondary distribution, and we respect those restrictions.
