This book is thus about “who we are” not only demographically, but also in terms of the past, especially how and whether we teach discredited pasts through textbooks. The authors discuss portrayals of past exclusions around religion, ethnicity, sexual orientation, as they look at the shifting boundaries of insider and outsider. But they all consider the changing portrayal of diversity, belonging and exclusion in multiethnic and diverse societies where silenced, invisible, marginalized members have struggled to make their voices heard and to have their identities incorporated into the national narrative.
I tried to select only the works in book formats, 'real' books that are mainly in PDF format, so many well-known html-based mathematics web pages and online tutorials are left out. Authors’ voices come from a variety of contexts – some historical, some contemporary, some providing analyses over time. Here is an unordered list of online mathematics books, textbooks, monographs, lecture notes, and other mathematics related documents freely available on the web. In some wealthier nations, the sale of printed books has decreased. This book engages readers in thirteen conversations presented by authors from around the world regarding the role that textbooks play in helping readers imagine membership in the nation. Google has estimated that by 2010, approximately 130,000,000 titles had been published.
