Indexers work from a Netscape-based indexing tool which feeds book index terms and their context.
Automated mappings are also retrieved through UMLS mapping. Indexers are also expected to process book terms within an agreed upon time frame and averaged time per term. Work weeks are seven days, Monday through Sunday, and the indexing tool is usually available 24-hours per day. Assignments are based upon processing an average of 25 terms per hour. Busy periods and periods with no work should be expected.
