Scope and Content of Collection
These field books contain detailed descriptions of real, personal and other taxes collected by Contra Costa County. Some are
labeled “duplicate copy”. Others are labeled “Supplemental Assessment Book”. Some volumes use separate empty pages within
the volume to include “delinquent taxes”, often for a previous year. Certain volumes are exclusively Poll Taxes; others include
the Poll tax within the primary volume. All show internal evidence of being the original bound books used by the tax collector,
containing notes, scribbles and marks to show that they had been copied into a final, clean assessment book. Only three final
books are currently in the collection, obtained by gift in December, 2015. See Guide to Collection for more details.
