It was probably the publication of Postmodern Pooh, Frederick Crews's second venture into Pooh studies, that explains the renewed availability of The Pooh Perplex more than 40 years after its first appearance. But whatever the reason, it is an excellent thing that modern readers can get hold of it, both because it is a brilliant and witty book in itself and also because it makes a natural companion for Postmodern Pooh.
For those who have not met the book before it should be explained that it is a series of parodies of different styles of literary criticism (those that were fashionable in the 1960s) applied to Winnie-the-Pooh and The House at Pooh Corner, collected together as a "case book" of the kind that was then popular for elementary English courses, and accompanied by Questions and Study Projects prepared by the editor, ostensibly Crews himself, but in reality as much of a parody as the articles themselves.
No doubt one would need to be familiar already with the parodied styles to get the most from the book, but no matter; one can get a great deal of amusement from it without any specialist knowledge, and some of the sources are fairly obvious even to non-specialists, the Freudian analysis by "Karl Anschauung", for example, or the proletarian analysis by "Martin Tempralis". On the other hand, readers born since the book was written may not easily recognize F. R. Leavis thinly disguised as "Simon Lacerous".
The non-specialist reader will easily be tempted to believe that Crews is exaggerating. Surely no serious expert on English literature could really express some of the sillier ideas expressed in this book? Alas, he amply demonstrates with real quotations from real (and apparently serious) publications that they could and they did.
