The Spokane County Brand Books were indexed by EWGS member, Beverly Hixson Rowley, in 1989 at the Spokane County Courthouse. The 2 volumes are now housed at the Eastern Regional Branch of the Washington State Archives. The index was originally published in the EWGS Bulletin, v. 26, pp. 9-17 and 60-64, 1989, and v. 27, pp. 131-135, 1990. Open file here.

Files were microfilmed in the 1970's and the originals destroyed. Book one was a catalog of papers concerning each court case, insanity, minors, estates of deceased persons, and adoptions. Only those concerning deceased persons were abstracted by Lorena Wildman in 1973. These listings are supported by case packets filled with all applicable papers for each case. The cases cover the years 1880-1903. Pages noted refer to the Memorandum of Files. The originals of these files are now housed at the Eastern Regional Branch of the Washington State Archives. The index was originally published in the EWGS Bulletin v. 23, pp. 113-122, 1986.
