+COMMENT ON FUNCTION migration_tools.make_stub_bib (text[], text[], text[], text[]) IS $$Simple function to create a stub MARCXML bib from a set of columns.
+The first argument is an array of tag/subfield specifiers, e.g., ARRAY['001', '245a', '500a'].
+The second argument is an array of text containing the values to plug into indicator 1 for each field.  
+The third argument is an array of text containing the values to plug into indicator 2 for each field.  
+The fourth argument is an array of text containing the values to plug into each field.  
+If the value for a given field is NULL or the empty string, it is not inserted.
