The Kansas Collection has the tax rolls for land in Douglas County and Lawrence, Kansas, for the years 1863-1967. The Lawrence volumes are arranged by subdivision, legal description, and address (later years) and the Douglas County volumes are arranged by the legal description of the property. The volumes show the name of the owner and the person who paid the taxes year by year, the amount of taxes paid, and the assessed value of the land parcel. These can be very useful for someone attempting to determine what year a house was built because of the corresponding increase in the assessed value. Occasionally additional information about the property is also noted on the entry.
