The journal replied, in terrible English, that my article would be accepted with changes requested by one of "two reviewers" supplying a short paragraph each. This request was that I shorten and focus the abstract, and format references.
The next thing I knew, I was sent an author proof. And an invoice for US$4,000. For some reason the illustration of Newburgh had been titled as being of Frederick Allen, a name which appears in the text but was never attached to any picture. I corrected this and received an authorproof with errors corrected.
Here is this proof, which I consider to be an accurate version of the paper, albeit I believe it was not properly peer-reviewed.
I never paid the fee, and received numerous reminders, not all addressed to me. I still receive emails from other OMICs journals requesting my input. I was never asked to sign a COI declaration of any sort, nor any other agreement (the work is Open Commons). I had read a thread on researchgate in which an author describes seeing their work published despite not paying the fee.
So I searched for my paper online and found it here.
Not only is the picture of Newburgh captioned Frederick Lewis Allen 1932, the references in the HTML version (but luckily not the pdf) are imported from some other paper, probably from a different journal.
I feel like this is a punishment to make an example of defaulting authors!
Anyway, the history of Newburgh is published, which is the main thing, but I feel ethically unclean, and whether anyone can ever now cite this article in a proper paper is uncertain. At least OMICs have not claimed exclusive rights in the matter, so republication is not out of the question. But then, if I'd thought this necessarily detailed history would be easy to publish in a proper journal, it would never have ended up in the hands of OMICs.
I'd like to thank Ash Simmonds and Zooko for introducing me to the work of Prof Newburgh.
