Detailed Publication Timeline

URL: Not captured — experimental run

Extract¶

Railsback provides the most detailed account of Chamberlin's publication history:

1890: Published in Science (old series), 15:92-96. Presented before the Society of Western Naturalists, October 25, 1889.
1897: Revised version in Journal of Geology, 5:837-848. Chamberlin noted it was "freely altered and abbreviated so as to limit it to aspects related to geological study."
1965: Reprinted in Science, 148:754-759.

The 1897 version is shorter and more focused on geological applications. The 1890 version is broader in scope.

Relevance to Hypotheses¶

Hypothesis	Relationship	Strength
H1	Supports	Strong — detailed confirmation of sub-claim C006a
H2	Neutral	Publication history is factual
H3	Contradicts	Strong — dates and venues fully confirmed

Context¶

Railsback's analysis provides the best available secondary account of the differences between versions. The 1890 full text was not directly readable (PDF binary), so Railsback's detailed analysis of the differences is particularly valuable.
