How long will it take to produce the index?
The time required to produce an index depends to some extent on:
Length of publication
Level of content
Number of index entries per page of text
Density of text (print size, amount of graphic material)
Additional research required to produce accurate entries
An average 200 page book written at a general level can be indexed in about 10 days.
More complex or longer texts require more time. Longer indexes also take more time to check and edit because of the complexity of inter-related entries:
For a 400 page more advanced text the index would take longer to compile and also more than twice as long to check and edit - in total around 3-4 weeks
