The first step in preparing the instances is to prepare the information for the collection-level finding aid. This is done by making a skeletal version of the finding aid with the headings, "agency history," "index terms," and a few others, and printing it out. Sometimes, notes are made directly on the print-out, filling in the blanks. Sometimes notes are made long-hand on cards and note paper. These are then entered into an XMetal instance with the help of notes and handouts from the SAA workshop, the Application Guidelines and Tag Library, and marked-up examples such as the William Fonds Provenance. The only thing used to proof and parse the instances is XMetal, on a PC. The indexing procedure is to make notes about possible terms, look them up in the Library of Congress's online catalog, using LC's heading when possible, and when not, constructing the heading based on AACR2.
