 @srfi[1]{List Library}
 
+This SRFI works with pairs and lists as in @schememodname[scheme] and
+@schememodname[mzscheme], which are immutable, so it does not export
+@schemeidfont{set-car!} and @schemeidfont{set-cdr!}. The other
+provided bindings that end in @schemeidfont{!} are equivalent to the
+corresponding bindings without @schemeidfont{!}.
