Time Constraints

How long to write an index?

• In order to write, edit and format an index, approximately one week (5 business days) is required for every 250 pages of text.
  
  
• A very "basic index" (i.e., short and shallow) may take just as long, if not longer to write as a comprehensive index. The "depth" of indexing varies with the page content, the audience and length of the index.
  
  
• The indexer is involved with many publishers and authors so it is important to schedule with the indexer with adequate lead time.
  

Editing of the index

• Editting takes between 20% to 40% of the total indexing time;


• Editting is a vital step, and readers will definitely notice if an index has not
  been given enough editing time;


• The more consistent and structured the main text is, the less time required


• Editting multi-authored works requires more time for editing because of
  differences in terminology, writing style and voice.

Factors than can increase the time required to index

• Complexity of the text such that a detailed comprehension of the text is
  required before indexing can proceed;
  
  
• Indexing of detailed notes or references;


• Requirement for non-standard house style format;


• Indexing of figures and tables;


• Poor quality page proofs, or awkward size or format that make reading
  difficult;


• Indexing reference and research text where the index needs to equal in
  importance the textual content of the document;


• Text with foreign language content;


• A poorly edited text;


• Changes in page numbering after the indexing process has begun;


• Late amendments to page proofs;


• Requirement to consult with the author.
