-       Keeping track of state of grid jobs.
+       <para>Logging and Bookkeeping (L&amp;B) service keeps track of grid jobs.</para>
+
+       <para>The service receives job events
+       from various components of the Workload Management System, stores
+       them, and derives then the corresponding job states.</para>
+       
+       Job information is fed into LB through a~logging interface
+       (<link linkend="">legacy C and shell API</link>)
+       and it is not exposed as a web service yet.
+
+       The users may query job states or retrieve LB events either via the same C/C++
+       interface or via this web-service interface.
+
+       Besides querying for the job state actively the user may also register for
+       receiving notifications on particular job state changes.
+       This functionality is supported only in the legacy C/C++ interface.
