14 Start: Begins With SELECT group_id FROM sorted_call_no_index WHERE call_number_search LIKE 'BD111.S30%' ORDER BY call_number_padded LIMIT 1

15 Start: Closest Match SELECT group_id FROM sorted_call_no_index WHERE call_number_padded > 'BD S30' AND classification = 'LC' AND call_number_padded != '' LIMIT 1;

16 Slice Web Service SELECT group_id, catalog_key, MIN(call_number) FROM sorted_call_no_index WHERE group_id BETWEEN – 0 AND GROUP BY group_id;

17 Slice Web Service SELECT group_id, catalog_key, MIN(call_number) FROM sorted_call_no_index WHERE group_id BETWEEN – 0 AND GROUP BY group_id;
