1. Item IV.E of Reference A explains Nodex percentages: "Computed by
comparing the number of documents nodexed (including Nodex-M's) and the number
of documents coded. Does not take into consideration TS, direct distribution,
and standard distribution. The figure is thus an indication of the amount
nodexed of those documents usually considered for indexing. It is not an
indication of the amount nodexed of all documents received."
2. Reference B discusses an alternate method of computation, which we
have not used.
