Index Generator will take a PDF book and produce a list of words with associated page numbers. If the book format is in some other form it must be converted to PDF (Microsoft Word offers this as a Save As option. OpenOffice also exports to PDF). Words can then be selected to be included in an index for the book. Individual pages of a word occurrence can be excluded or included. Words can be set to reference other words. Words can be a subheading of other words. Once the words have been selected, the output can be formatted to your liking. The index can be printed or saved as a Microsoft Word File, RTF File, Plain Text File or PDF File. The preview dialog allows coping to the clipboard for pasting into an application of your choosing.
