Word performs many tasks extremely well, but it fails in several areas when creating a complex book. The Master Document works beautifully to create table of contents and index for a short, simple document such as a booklet. As soon as a document includes a large number of large files, the Master Document falls apart, leaving the user wondering where he went wrong. It's possible to use work-arounds, but time spent figuring out ways to trick Word could be better applied to actually producing your book. When you are desktop publishing a right-justified book, Word has a major failing.
Word makes it difficult to adjust the space between letters within words in a line of type.
This means that you will occasionally have very strange-looking lines with large spaces between the words. In contrast, a desktop publishing program automatically adjusts not only the space between words, but also the space between letters in the words. Such a program also offers you kerning, a manual way to adjust space between letters or words. Finally, desktop-publishing programs allow tracking, a way of squeezing everything together a little tighter or loosening up a line of text. Word will let you manipulate the spaces between letters, but the effort is far greater than the easy steps in a true desktop publishing program.
