Field research

Scope and Content

The series comprises numbered and un-numbered field notebooks;specimen catalogues; sketchbooks, photograph albums, and maps.

Administrative / Biographical History

The records in this series reflect the work undertaken by Harker both when employed by the Geological Survey from 1895, and during the times he was engaged in teaching. They also cover the time when he had retired from both these activities.

Arrangement

The series has been arranged to reflect the ways in which Harker created and stored his records i.e. there is a clearly numbered sequence of notebooks covering expeditions which forms one sub-series, and others which do not fit into this but are either clearly labeled or identifiable, so make up other sub-series. These have been arranged chronologically, in keeping with the numbered series.
