5297 unique publication places; available for 1162776 documents (95%).
ambiguous publication places; some of these can be possibly resolved by checking that the the synonyme list does not contain multiple versions of the final name (case sensitive).
unknown place names These terms do not map to any known place on the synonyme list; either because they require further cleaning or have not yet been encountered in the analyses. Terms that are clearly not place names can be added to stopwords; borderline cases that are not accepted as place names can be added as NA on the synonyme list.
discarded place names These terms are potential place names but with a closer check have been explicitly rejected on the synonyme list
