-  Normally the Lisp reader interns all symbols (@pxref{Creating
-Symbols}).  To prevent interning, you can write @samp{#:} before the
-name of the symbol.
+  As an exception to the rule that a symbol's name serves as its
+printed representation, @samp{##} is the printed representation for an
+interned symbol whose name is an empty string.  Furthermore,
+@samp{#:@var{foo}} is the printed representation for an uninterned
+symbol whose name is @var{foo}.  (Normally, the Lisp reader interns
+all symbols; @pxref{Creating Symbols}.)
