The publishers have just informed informed me that the above book has been out of print since sept, 1993, that no stock is available, and that the copyright reverts to me. I would consider getting some loose page copies printed and sold if this seemed economic, and/or if for example there was a desire to use part or all for course adoption. For the latter I could supply a top copy and allow for copying to students at a moderate fee per student. Offers welcomed. The aim is to get the book available and read. The publisher's previous distribution at 50 pounds sterling discouraged this. This book has material on groupoids, homotopy types, fundamental groupoid of orbit spaces, etc. not available elsewhere.
