Back-of-the-book indexing, especially in the following subject areas:
Online reference (database) indexing
Periodical indexing, both in print and online
For back-of the-book indexes, payment is typically on a per-page rate in the range of $2.50 - $5.00 per page. Complexity of subject matters is a primary consideration in determining the rate. Indexes for trade books, professional books and higher education textbooks typically fall into the range of $3.00 - $4.00/page. Indexes for academic or scholarly books are typically $4.00 - $5.00/page, whereas children's reference and K-12 textbooks are usually only $2.50 - $3.00/page. Density of text per page is also taken into consideration in determining the exact rate.
For periodical indexing, as long as the indexing is to the article and not to the page, payment is on a per article rate, similar to the book per-page rate. For database indexing, either a per-record rate, similar to the book per-page rate, or an hourly rate is charged.
