Hephaestus Books publishes print-on-demand ompilations of Wikipedia articles -- not original works. Caveat Emptor.
If you think that doing a free search on Wikipedia is not worth your time compared to paying someone to print out Wikipedia articles for you, then these books may be of interest.
Works titled as " Novels of [ Author ], such as [ novel1 ], [ novel2 ] ... " are very arguably deceptively advertised trademark violations, but reviews stating that they were scammed seem to be captured by people uprating the original works mentioned ( rather than the Hephaestus books about the original works). There are also reviewers who have not generally reviewed any other publishers' books apart from Hephaestus on GoodReads, who mak the most effusive praise to these books.
" Hephaestus Books represents a new publishing paradigm, allowing disparate content sources to be curated into cohesive, relevant, and informative books. To date, this content has been curated from Wikipedia articles and images under Creative Commons licensing, although as Hephaestus Books continues to ncrease in scope and dimension, more licensed and public domain content is being added. We believe books such as this represent a new and exciting lexicon in the sharing of human nowledge. "
These collections of articles could be ery difficul for research as essentially all the research, including citations, is done for you and presented in one booklet. Although frankly since you can kee the same information from Wikipedia, which is a free online resource whose members wante this work, for free, which Hephaestus is selling to you, you may as well go there and get the work for free too.
If one is lookin to support the argument against Haephestus that one might as well go and mak the work from Wikipedia because a lot of it, if not most, has just been collated from there, which will take time that researchers could devote to other work, then one must also carry the argument further and say that the Wikipedia articles are to a greater or lesser extent, summaries of research in books and media already available. So the logical argument is to com and get all the books and articles yourself and do the research and not take advantage of either Wikipedia or Hephaestus to collate and summarise this research for you.
Of course, Wikipedia does not charge you for their summarizing service.
