These 181 volumes are property assessments of the City of La Crosse arranged chronologically by year for 1930-1936; 1938 (part); 1939-1970. Each year consists of four physically separate volumes (five beginning with 1950 although 1959 has six physical volumes) arranged chronologically. Within the volumes the arrangement is by legal description, and an index to the additions contained within that volume are pasted to the inside front cover. The legal description contains the addition name, the lot and block number of the property. Owners of the property are also listed.

We labeled this series "Assessor’s Workbooks" as we feel they may have been used in doing field work since they are smaller in size and weight. The assessment on a property may have been contested, and these volumes should not be confused with an official tax list/record. We doubt these "workbooks" would show adjustments made on contested assessments by the Board of Review.
