The Churchill report is much worth reading -- it's long, but quite interesting and strikes me as quite persuasive (though I should stress that I haven't checked the sources myself).
Here's an interesting item that I haven't seen much discussed: Churchill is found guilty of passing off others' work as his own (plagiarism), but also of passing off his own work as others'. The latter is faulted as a general departure from "established standards regarding author names on publications" (p. 89); but it's also more specifically, and more seriously, faulted because Churchill then used the work published under another's name "as apparently independent authority for claims that he makes in his own later scholarship" (p. 89). This "permits the author to create the false appearance that his claims are supported by other scholars when, in fact, he is the only source for such claims" (p. 90). Here's an example, from pp. 23-24 (some paragraph breaks and emphasis added):
Footnotes 63 and 64 of his “Perversions of Justice,” in Struggle for the Land (1993 edition), contain basically three sources to support the claims regarding the General Allotment Act of 1887. All appear to the reader to be reputable, independent third-party sources.
First, Professor Churchill cites directly to the originally enacted version of the General Allotment Act of 1887 .... [But n]ot only is his statement unsupported by his source, but also more significantly, he did not follow the referencing convention that a lawyer or historian citing a lengthy statute for a particular detail normally would follow, which is to pinpoint the precise section number of the multi-section statute that supported his claim. As one will see throughout this report, this general reference to an apparent independent source in its entirety constitutes an unconventional referencing style frequently employed by Professor Churchill to create the appearance of independent support for his claims, while simultaneously discouraging or, at least, making far more difficult, any effort by other researchers to check his claims by failing to pinpoint the precise location of his claimed support in an otherwise lengthy work. Standing alone, this referencing failure might constitute some level of sloppiness, but certainly would not constitute research misconduct.
When it is combined with a pattern of other misconduct reflected in this and other allegations, however, the Committee is left with a firm impression, by a preponderance of the evidence, that it constituted part of a deliberate research stratagem to create the appearance of independent verifiable support for claims that could not be supported through existing primary and secondary sources. To put it most simply, it was part of a pattern and consistent research stratagem to cloak extreme, unsupportable, propaganda-like claims of fact that support Professor Churchill’s legal and political claims with the aura of authentic scholarly research by referencing apparently (but not actually) supportive independent third-party sources. The next problem discussed with these two footnotes makes this stratagem far clearer.
The other two apparently independent third-party sources cited in footnotes 63 and 64 are essays published in the same volume, The State of Native America, one under the name of a person named Rebecca Robbins and the other under the name of M. Annette Jaimes, the editor of the volume. Since both essays do contain statements of the type that Professor Churchill claims, that might have put an end to the matter of research misconduct regarding this allegation, except for the fact that in response to the separate allegation that he had plagiarized the Robbins essay in another later published piece, Professor Churchill said in Submission E that he had in fact ghostwritten both the Robbins and the Jaimes essays, in full.... [This] constitutes a serious problem of research misconduct. The initial support for the disputed statement involved three independent sources. As already noted, the Act does not expressly provide what Professor Churchill claims and therefore can provide no support for his claims whatsoever. The two other apparently independent third-party sources, the Robbins and Jaimes essays, turn out not to be independent sources at all but, rather, to have been ghostwritten in their entirety by Professor Churchill. This action provided him with apparent independent sources that he could and did in fact cite to support otherwise insupportable claims of legal and historical fact. In short, when one carefully dissects the Churchill claim quoted in the original allegation, the three apparently independent third-party sources dissolve into one source (the Act) that clearly does not expressly support his claim, and two other sources (the Robbins and Jaimes chapters) that he wrote himself.
Although Professor Churchill purported to offer his claims as supported by research, based on independent sources, it turns out that the claims not only cannot be supported but that he has misrepresented the independent nature of his sources employed to buttress the unsupportable details of his conclusions....
