Hi Astro44! I think that the one book All Sky edition must be different. I have searched and searched... The first 6 pages are index charts, then one page Constellation summary, then next page is title page saying All Sky Edition, then acknowledgements, then Introduction on page 1 going through to page 10, then the main charts start - 1 to 220, then the A series....No Roman numerals . I have read the introduction several times and cant see anything buried in there! Frustrating....
