Strange encounters of the write.as kind
LP: Until the middle of the 19th century, writing in books was not considered defacement. Now you wouldn’t want to be seen writing in a library book any more than you would want to be seen putting your feet up on the library desk. But in Milton’s time, writing in a book was not considered damaging it; it was considered enriching. If you were a schoolchild who didn’t write in your book, that would have been seen as somewhat lazy, a sign you were not really engaging.
