A complete photographic record of Professor Beyer's collection of Chinese ceramics and Philippine pottery; photographs of Philippine tools, weapons, costume, artefacts, villages, houses, hunting, temples, burial practices, weaving, dances, musical instruments; photographs of official visitors, and Professor Beyer and friends. Many of the photographs were taken by Professor Beyer.
The H. Otley Beyer Map Collection consists primarily of maps collected by Beyer of the Philippines. The collection includes rainfall, topographic, land-use, language groups, ethnic groups, geological maps and road maps. There are a small number of manuscript maps about ethnic groups and language groups of the Philippines, as well as tektite sites, some of which were authored by Beyer. In addition, a small number of maps have been kept with the Beyer manuscript collection (Papers of H. Otley Beyer, 1850-1964, MS 4877).
