Reading about the Portuguese author Maria Amália Vaz de Carvalho, I came across the following interesting tidbit of information:
The collection of stories for children she wrote with her husband, Contos para os nossos filhos ("Tales for our Children", 1886) was approved by the Board of Public Instruction for use in schools.
Unfortunately, Wikipedia provides no citation for this claim, and I haven't been able to find out any more information online (I tried searching for the author's name together with "tales for our children" and together with "schools"). How exactly was a book of short stories "use[d] in schools"? Were the stories educational in nature, was it a "cautionary tales" type collection, or were they simply studied in literature class, presumably together with more classical works?
