['ANP', 'BYVANCK', 'DPO', 'SGD']
>>> records = oai.list_records("ANP")
>>> records.identifiers[:3]
['anp:1937:10:01:1', 'anp:1937:10:01:2', 'anp:1937:10:01:3']
>>> len(oai.resumptiontoken)
42
>>> record = oai.get(records.identifiers[0])
>>> alto_record = record.alto
>>> alto_to_text(alto_record[0]).split("\\n")[1][:27]
