Sonar Bookends is designed to ease the tedious task of creating indexes for long documents. The package provides some unique and powerful tools, but interface flaws and a lack of editing tools detract from the program's overall usefulness, Bookends automatically creates an index based on every word in a document. You can eliminate common words such as a or the by setting the program to ignore words appeari ng a certain number of times.
Unlike the indexing methods used by some word processors such as Microsoft Word or WordPerfect. Bookends' method requires no special characters or marking procedures to tag words for indexing. The drawback, however, is that Bookends' indexes are likely to include multiple unwanted entries.
Bookends also lets you create a separate phrase list for indexing. Although creating a phrase list may initially seem as time-consuming as using a word processor's indexing method, Bookends balances the inconvenience with some superior phrase-list features.
Using special characters. Bookends provides an impressive variety of Boolean selection options for creating phrase lists. For example, you can specify any variation of the word Apple, such as Apples and Apple's, to be included as part of the same index entry. Or you can specify words such as John Sculley and Sculley, John to be indexed together regardless of order of appearance. You can even specify the indexing of the words John Sculley in any order and appearing within ten words of the entry Apple or Macintosh. Although this requires some effort to set up, it really saves time in the long run. But despite these strengths, Bookends does a poor job of following Apple's interface guidelines. Equally disappointing is the lack of editing tools. To clean up indexes, you must use a word processor.
The result is that most users of word processors with built-in indexing will probably prefer to stick with them. However, Bookends is a good choice if you don't have a word processor with built-in indexing or if you require the package's unique abilities.
