Change it to:

 As you can see, there is some order again but I don't have to know the
 order. (Finding any book (and then another arbitrary book from the remainder)
 is the job of the librarian, not mine.)

And that should be precise enough for everyone here.

There is no first book as such in the set. There is only the first one that
was given to you, which is not knowable in advance.
