The popularity of the First Edition of this book has been very gratifying. It confirms that there is a genuine need for a text covering the magnetic bubble technology. We are pleased that the readers have found that this book satisfies that need. It has been used as a text for courses in both universities and industry, and as a reference manual by workers active in the field. To meet the need for more copies of the book it seemed preferable to publish a second edition rather than merely a second printing. There has been some significant progress, even in the short time since the initial printing, and we wanted to include that. At the same time we would like to provide the new copies at the lowest possible cost so that they are more easily obtained by students. For this reason the new edition is in soft cover and the recent progress has been described in a final chapter rather than incorporated into the original chapters. This eliminates the expense of resetting and repaging the original text. At the same time up-to-date references have been added and typographical errors have been corrected in the original chapters. It is our hope that this edition will be useful to those with an interest in the fascinating field of magnetic bubbles.
