This library page is still growing. It is presently a list, with links if available, of books, papers or presentations by or involving Keeper Trout.
IMPORTANT CAUTION TO READERS OF OUR PDF BOOKS.
Our former domain at largelyaccurateinformationmedia was purchased by someone who added some sort of malware that now responds to the download links in our older PDFs.
Please do not use any links to that site. All PDF copies are available for free through us and have been replaced with newer copies lacking those old URLs. Please download new copies to replace the pre-existing ones.
It was recently brought to my attention that our book PDF links stopped working. The files are all present at the specified URLs but the links to them were for some reason not connecting and are giving an error message that the files can’t be found. While I puzzle over this and correct it, here is a simple set of direct links to copies of those same files (my thanks to Endlessness for letting me know!):
