Summary:  AMS packages that replaced AMSIbTEX, version 1.1, but the book still had an AMSIbTEXcentric view. This third edition is about IbTEX. Where necessary, I recommend that you use packages to extend IbTEX's capabilities. For typesetting mathematics, I strongly recommend that you use the AMS packages. AMS packages, version 2.0 The American Mathematical Society released version 2.0 ofthe AMS packages in 1999. This third edition covers the changes made in this release. Books The first and second editions of this book dealt primarily with the tasks involved in writing artides. In Part V, the third edition addresses the issues that arise when creating longer documents. In addition to chapters on BIBTEX and Makelndex, I have added a new chapter on writing books. Appendix F illustrates the impor tance of choosing a welldesigned book document dass. Other changes B\1EX IbTEX2 has been remarkably stable since its release in 1996, becorning c the standard IbTEX (see Section C.1.2). Changeshave been rninor except for ad vances in using IbTEX with nonEnglish languages (see the new Appendix E) and the widespread use of the PostScript CM and AMS fonts (see the new Section D.l). Reorganization and additions Due to the new emphasis on writing books, a number of sections and subsections have moved from Chapter 2 and Chapters 68 to the new Chapter 12
