I happened to notice that different books published by Springer sometimes have slightly different names listed next to the copyright © symbol. For instance:
Mirrors and Reflections by Borovik and Borovik says © Springer Science+ Business Media, LLC 2010
Combinatorics of Coxeter Groups by Bjorner and Brenti says © 2005 Springer Science+Business Media, Inc.
Limits, Series, and Fractional Part Integrals by Furdui says © Springer Science+Business Media New York 2013
In the first example we have "LLC", in the second "Inc.", and in the third the place of publication (I think?) "New York". There's also a space between the "+" symbol and "Business" in the first example, which is not there in the other two.
I know these are really minor differences that won't come up in any matter of significance. It's just that I'm curious and want to know why there are these minor differences. I would expect the name printed on the copyright page to be standardised so I found it surprising to see (what looks like) inconsistencies and typos.
What is the reason for these differences in the copyright information?
Some additional information which might or might not be relevant:
These are all Mathematics textbooks. The first belongs to the series Universitext, the second to GTM (Graduate Texts in Mathematics), and the third to PBM (Problem Books in Mathematics). However, the differences are not consistent across the different series (one can check by going through other books in the links above).
The Wikipedia page on Springer mentions that Springer Science+Business Media became a part of Springer Nature through a series of mergers, but that happened in 2015, which is after the dates of publication of my examples.
I have tried looking up the difference between LLC and Inc. on the web, but I haven’t understood enough to be able to point out anything of help.
I searched for related questions on the SE network (specifically on Law SE, Academia SE and Mathematics SE) and found the following question on Academia SE that is related but significantly different: Referencing Springer products: what name to use for the publisher?
