+MKWS accesses targets using the Pazpar2 metasearching engine. Although
+Pazpar2 can be used directly, using a statically configured set of
+targets, this usage is unusual. More often, Pazpar2 is fronted by the
+Service Proxy (SP), which manages authentication, sessions, target
+selection, etc.
+
+This document assumes the SP is used, and explains how to go about

+MKWS application to that library, and how to choose which of the
+available targets to use.

-1. Selecting targets within the library

+2. Choosing targets from the library
+------------------------------------
MKWS applications can choose what subset of the library's targets to
use, by means of several alternative settings on individual widgets or

Some MKWS applications will be content to use the default library with
