This book is not only rare, but also has been printed on very weak paper. The copy held in the Baker Papers (PMB 1203/227) is disintegrating. The copy held by the National Library of Australia, microfilmed here, is in better condition but the paper is very fragile and has cracked in several places. Other surviving copies are also likely to be deteriorating due to the poor quality of the paper. The PMB also has available a digital version of Baker’s Tongan Vocabulary, scanned from this microfilm, converted to text, and searchable.
