Yes, it is! I somehow missed that when checking the IUCr web site.
Virtually the whole publication is available as a series of
downloadable PDF files, though for some strange reason the indices
are listed but not available. Without the Name Index it would have
taken a huge amount of time to locate the pertinent sections in a 700
page book.
