Booklist Online expects reviewers to be from the USA or Canada, but the others are more open. BookBrowse, for example, include the following statement "Most of our reviewers are USA based, as is BookBrowse. But we are open to reviewers overseas. However, because we work exclusively with American publishers, it is rare that the publishers can send print copies to addresses outside of the USA. So if you live elsewhere only apply if you have the ability to read ebooks and are comfortable doing so."
