Each poem is fourteen lines long, though not all present themselves as traditional sonnets; a poem may be seven couplets, for instance, or two stanzas of seven lines. The poems are playfully and wittily self-aware, linguistically savvy.
I particularly liked Van Doren's syntax, which is usually graceful and clever. Pound says somewhere that poetry should be at least as well-written as good prose -- a principle he obviously decided to jettison by the time he composed the Cantos, but I wish more poets followed it more often. There's a honored place for the paratactic, of course, but I wish poets who do use ordinary syntax would pay it at least as much mind as they do their lineation, over which so many obviously agonize, meanwhile letting modifiers dangle and squint.
A likable book, though not an exciting one.
