386.05 Tract index books.
Every county board may procure at the expense of its county, and keep in the office of the county recorder, suitable books, substantially bound, arranged in numerical order, and so ruled that opposite to the description of each section of land or sectional lot, and town or city lot and block, shall be a blank space, of a convenient size, in which shall be entered the letters or numericals indicating the volume of the records referred to, designating deeds by the letter "D," and mortgages by the letter "M," or by using red ink for mortgages and black ink for deeds, and other records by appropriate initials or abbreviations, together with the page of the volume upon which every record affecting the title to the whole or any part thereof may be found. Such tract index shall be kept as one of the records in the office of the county recorder, and such recorder shall note therein a like minute of every instrument affecting the title to any land which shall be filed for record, to be made opposite to each parcel of land the title to which may be affected by such instrument. Instead of causing a tract index to be made, the board may purchase any existing tract index or abstracts; and thereafter the recorder shall make the appropriate entries therein. In either such case the recorder may make abstracts, for persons demanding the same.
