Diff between Ryden's two 'Introduction to Cosmology' books?

[hobboy]

Barbara Ryden seems to have two Cosmology books, her one https://www.amazon.com/dp/0805389121/?tag=pfamazon01-20 and one https://www.amazon.com/dp/129203971X/?tag=pfamazon01-20. I haven't been able to find any differences between the books online - the 2013 book doesn't seem to be a new edition of the older book. Surely 10 years would bring some new material, but I don't want to have to buy it to find out. Does anyone know anything about this new book?

Alternatively, would anyone recommend the newer book? The older one seem quite good and I can borrow it from the library, but I'd like to get the newer one if it's worth the money.

From the links you posted... the 2003 links to a hardcover book and the 2013 links to a softcover book.
The 2013 link cover image says "First Edition" on it.

Here are google book links [from looking for the isbns on google books]:
2003 https://books.google.com/books?id=z27vAAAAMAAJ ... says it has 244 pages; illustrated
2013 https://books.google.com/books?id=DtZCnwEACAAJ ... says it has 264 pages; illustrated, revised ; international edition
