Algum material do professor William Trench

Há alguns meses recebi um email do autor destes textos que me pediu para divulgar esta informação.
Passei os olhos. Gostei de algumas das coisas que vi e reencaminhei para vários amigos e colegas, e agora, passados alguns meses deixo a informação aqui no blog, disponível para toda a gente.
