There were a number of recognized methods in use. Some were very down-to-earth. When a medium visited a new town, he was advised to visit the local cemetery and make a note of names, dates, and any other information to be obtained from the tombstones. He might also consult the "Blue Book" for the area, a compilation circulated among mediums listing, for an increasing number of places, the names of leading spiritualists likely to attend seances, with descriptions, family histories, and details (deceased spouses, children, parents, etc.) and other information likely to be of use.
