When I was in public school (1960s-1970s) we were required to wrap our textbooks, since they were reused for years. I got really good at making wrappers from butcher paper or used shopping bags. In college it was normal to purchase cheap decorated covers, but only for hardback textbooks; if your paperback Norton Anthology of English Literature survived the semester, good luck to whoever bought it next.
I recognized quite a few poems...there are a lot of US based authors, but looking back 100 years I guess you would have: UK, Australia, USA, parts of Canada. Both the US & UK are well represented, and population wise I don't know how much poetry the other ones crank out. I recognized a lot of poems from the Norton Anthology of English Literature.
