Office XP for Business
According to OER Commons, this is a "manual to support students in using the Microsoft Office XP operating system and the Microsoft Office 2003 software suite. In many developing countries IS textbooks tend to be expensive despite the best and, I believe, sincere efforts of educational publishers to keep their developing country rates as low as humanly possible. This book (except for the Access section) has been released under the Creative Commons license, i.e. it is freely available for (educational) use to anyone who wants it."
