 Despite the criticism , Clausen observes that " ' Mrs. Beeton ' has ... been for over a century the standard English cookbook , frequently outselling every other book but the Bible " . According to the Oxford English Dictionary , the term Mrs Beeton became used as a generic name for " an authority on cooking and domestic subjects " as early as 1891 , and Beetham opines that " ' Mrs. Beeton ' became a trade mark , a brand name " . In a review by Gavin Koh published in a 2009 issue of The BMJ , Mrs Beeton 's Book of Household Management was labelled a medical classic . In Isabella 's " attempt to educate the average reader about common medical complaints and their management " , Koh argues , " she preceded the family health guides of today " . Robin Wensley , a professor of strategic management , believes that Isabella 's advice and guidance on household management can also be applied to business management , and her lessons on the subject have stood the test of time better than some of her advice on cooking or etiquette .
