If it’s a Western-style book, yes that is so! And by ascending numerical order, I mean number 1 on the left side. When you put English language Book One on the shelf spine facing out, its cover gets turned to the right side (unless it is upside-down!), touching back cover of Book Two. But Manga will have front cover of Book One snug against the left side of the bookshelf, and its back cover touches front cover of Book Two. You should go try it with your books, just to see it happen. Feels good.
isn’t it the beginning of one book touching the end of the next if they are in ascending numerical order?
