A very good question. In the US, this book is out of print and difficult to locate at a reasonable price. The few new copies that can be found are going for well more than retail price - in some cases up to 3x. Logos has an electronic version available but I seem to prefer print books for reading over the electronic versions.
Their is a lot of buzz about the reprint of Culver; but I know nothing about him and his systematics. What does Culver deal with in a distinctive way that justifies my putting him on my shelf beside Hodge, Hoeksema, Kersten, Mueller, Calvin & Turretin?
