The term "commonplace book" is commonplace, but I had never heard "zibaldone," which I now know as a variant also called a "hodgepodge book." Leopardi compiled a famous one, apparently. They go back a ways, such as to 14th-century Venice. I like this term and think I'll adopt it. Been a hodgepodger my whole life.
Have not read Derrida. Have known deconstruction only as a target of derision. This makes me think I should pay more attention to what the gentleman had to say.
Impressed by every page of The Continuous Katherine Mortinhoe by D. G. Compton. Smart, imaginative, superbly crafted, astringent. Buy it in the bookstore. I wouldn't steer you wrong.
