+%%%%% MN.BST version 1.1b, 19/07/95
+%%%%% John Sleath and Tim Jenness, MRAO, Cambridge
+%%
+%% Bibliography style file for MNRAS.
+%%
+%% Gives correct style for all entries (as far as known!). However,
+%% the sorting of two- and three- author papers, with the same first
+%% author does not (quite) conform to the correct style.
+%%
+%% Use \cite to give (Smith \& Jones 1995) or \shortcite to give the year
+%% (in brackets) only. This file should be used in conjunction with
+%% mn.sty (Blackwell Scientific).
+%%
+%% Extensively modified from astron.bst and apalike.bst
