Bookvika Publishing is one of a number of print on demand publishing companies or 'imprints' of those companies. It advertises titles that are printed off as physical books once payment is received, on online booksellers, including Amazon.
All of Bookvika's titles are copied from Wikipedia using automated software, usually without any subsequent editing of Wikipedia content. They contain, therefore, material freely available online but packaged between two covers as a book.
The two "editors" or "authors" of all Bookvika products are, as of December 2012, Jesse Russell and Ronald Cohn. Amazon.com in the USA lists 185,225 publications by Ronald Cohn., suggesting this is the current extent of the Bookvika offering.
The Bookvika.com domain name is listed in Moscow but inactive.
