However, I think the slowdown I was getting is a different problem. I don't know enough about how Z39.50 servers actually work, but I think that requesting each book in turn just had a high overhead of network traffic,
Correct. If you request a total of ten records one at a time then that equates to ten request/response conversations between client and server. This realy is very wasteful of network and server resources. It is for reasons of efficiency that z39.50 allows you to ask for multiple records from the server in one fell swoop. (A server may limit the number of records it will return in any one reuqest, but I wouldn't have thought 20 records would cause any server a problem (unless they are very large records.))
