Category Description This category contains the sites of commercial enterprises focused primarily on creating indexes for written materials.
Please note that sites offering these services
as well as other writing services will be listed instead in the
Editing and Proofreading category, or even the
Writing and Editing category, depending on how broad their focus is. In addition, sites offering indexing services
primarily to a specific field will be found with other sites related to that field. (Look in the
Writing and Editing category to see which fields have a separate category.)
