 actually, you are making OR, as you did not calculate whether Google books has more scholars or writers. Please cite your sources. Secondly, there is no requirement of ""full professors"" or scholars  as long as its a reputable publishing house, a major source, and is verifiable, it satisfies the requirement. Please cite your objections using Wikipedia rules in case you think I misunderstood Wikipedia rules or missed an additional clause. Thanks.  "
