The YAZ Proxy can be used for a number of different purposes, but perhaps one of its most interesting features is that it can make any Z39.50 server look like a (SRU/SRW) webservice. If you have a Z39.50 server you'd like to access but you're intimidated by the protocol, use the proxy and you can submit queries like this 
and get results back in XML. A SOAP-based protocol (SRW) is also suported. The proxy is used by the Library of Congress and other major libraries."
