Title: this little book is really great but...
Review: Yes, this little book is really great. It's complied pretty well. Though I still wonder what is the difference with the later edition of 1980, as it is told in worldcat website that's enlarged, revised and illustrated.My point is to understand it and even more - I have a real misunderstanding about the author whether it is James Hall, Julia M Ehresmann or someone else.Of course, it would be secondary if I knew which of the editions is really full...At amazon books both are mentioned as authors and editors of the editions of 1961, 1964, 1971, 1979.PLEASE, LET ME KNOW WHAT IS WHAT AND WHO IS WHO... I'D LIKE TO BUY THE LATEST EDITION OF 1980 (?).Thank you in advance and forgive me, it's more a question then a review, but still...
