Alan Libert: 'A Priori Artificial Languages' recommendable?

Hi!

Does anyone know the following book?  Is it recommendable?

> LW 24: A Priori Artificial Languages

> University of Newcastle
>
> The best known artificial language is Esperanto. However, hundreds
> of other artificial languages have been proposed, although some have
> not progressed beyond the stage of sketches and few have seen much
> actual use. Those which are not consciously based on natural
> languages are called a priori languages. Such languages have been
> less successful than artificial languages built with elements of
> natural languages, such as Esperanto and Interlingua.
>
> However, a priori languages are of considerable theoretical
> interest, in particular from the point of view of language
> universals: if a universal property holds even of languages created
> "from scratch", then it can indeed be seen as a property of any
> (usable) human language. Therefore, in the description of the
> grammars of several a priori languages, particular attention will be
> given to whether their features are in accord with proposed
> universals, of both the Greenbergian and Chomskyan types.
>
> After an introduction one chapter each will be devoted to
> phonetics/phonology, writing systems, lexicon, morphology, syntax,
> and semantics. The languages described include aUI, Babm, Fitusa,
> Loglan/Lojban, and Suma. Most of these languages have received very
> little attention, even from scholars studying artificial languages.
