'The volume presents a very useful discussion of the methodology of linguistic subgrouping, methods of computational cladistics and the features allowing the establishment of the individual subbranches of Indo-European and speaking for or against possible higher intermediate nodes.' Daniel Kölligan, Folia Linguistica

'This is an outstandingly valuable book, bringing together facts and hypotheses which have been scattered through the professional literature. It will surely become a convenient reference source and a starting-point for scholars who develop new hypotheses in this field.' Geoffrey Sampson, The Linguist List

'Olander and crew have provided us with a set of very fine analyses of the major issues in Indo-European subgrouping, and the extensive bibliographies themselves might be said to be worth the price of admission. No one will agree with all the conclusions, but the evidence is there for all to see and further development of the question, whether to reinforce the syntheses presented here or to forge new ones, must take this book as a point of reference.' Douglas Adams, The Journal of Indo-European Studies
