John: I suggest you stay right away from using a list of keywords generated from one book to automatically add index markers to another book for a few reasons.
First, you will find when you apply the list of keywords to the second book that there will be many false hits which you will have to remove/edit tediously by hand. Second, by convention, entries in indexes should conform to the universal convention of plural forms for nouns, and the gerund (or present continuous tense) for verbs, thus --- cats caring for feeding of etc. In the second and subsequent books, target words are likely to be in various forms so words which should be hits will be overlooked. Third, good index entries are typically fragments containing several words (e.g. "configuring modems"), so attempting to apply fragments to a book will again miss many valid hits. There is a long history of unsuccessful attempts to automate indexing (look up KWOC and KWIC for early examples) and IXgen is no exception. The only successful attempt is Google. 8^) An index compiled by a human indexer will always be of superior quality. May I suggest an alternative strategy? User guides and other user-oriented publications typically differ from other kinds of books by fairly short blocks of text or instructions ("topics") and large numbers of headings, usually nested deeply. And each heading is usually a good description of the contents of its topic. Therefore, an index based on only these headings should produce a high-quality index as there should be little need to create index entries for phrases and concepts within the topics. 1 Consider creating a special book containing all the component files from the other books. 2 Then use IXgen's ability to attach markers to the heading paragraph formats, embedding the text of the heading within the marker. 3 Generate the list of markers. 4 Edit each entry in the list of markers using the standard syntax for marker text. 5 Update the markers in the book by writing them back, making sure to split markers containing multiple entries into separate markers. 6 Read the markers back into a new list of markers sorted alphabetically. 7 Edit the markers for consistency and to combine clones, etc. as you would normally. 8 Generate individual indexes for each of the three separate books. 9 Read through each book and add extra index entries for concepts, etc. within topics that really are important enough to be indexed. The master index already generated will ensure that these final entries are consistent. This should produce consistent indexes in all your books for far less effort than applying a list of keywords and editing the subsequent list of hundreds of (mostly) false hits.
