This volume contains charts 101-134, which were not shown on the printed index map. No OIM created.

volume 2:

Images - https://geo.btaa.org/catalog/p16022coll230:261
OIM record - https://geo.btaa.org/catalog/p16022coll230:261-index
OIM in GitHub - https://github.com/geobtaa/openindexmaps/blob/main/p16022coll230:261.geojson

The OIM is incomplete, because some charts were not included in the atlas. Charts 135-141 are also missing because they were not present in the printed index map.
