There are 21 research papers in the collection, some of which were presented at a special session at the AMS meeting in Baltimore in January 2003. Two of the papers are by Rahman, both co-authored with Gasper. There is also a valuable survey of Rahman's work by the editors and Richard Askey, and some other biographical material. I did not know that Rahman is an award-winning Bengali writer as well, and I think that a translation of one of his shorter essays would have been a nice addition. Rahman started out working in mathematical physics before migrating into special functions, and once he started thinking about q-series he never stopped. He soon became one of the world's foremost experts, a distinction that, thanks to Basic Hypergeometric Series, he will hold in perpetuity.
Thus it is fitting that most of the papers in the collection are on some aspect of q-series. Naturally I have my favorites: I would read George Andrews or Bruce Berndt if they wrote about sheep farming, there are several other authors here whose work I always enjoy, and I am especially glad to have the paper of Michael Schlosser. It would be presumptuous of me to make further judgments about the papers; suffice it to say that many world leaders in special functions have contributed, and the overall quality is very high. Anyone working in q-series should own this collection. It may also be of interest to people in other areas within or related to special functions.
