(1) ``Introduction to Cosmology, 2nd Edition'', by Barbara Ryden [hereafter abbreviated as Ry], 2017, Cambridge University Press (UK), York), ISBN: 978-1-107-15483-4, hardback, costs about $ 44-58 to buy new or $ 23-43 to rent (the price range indicates used-new). Do NOT buy the 1st edition from 2003, as it is no longer up-to-date. Ryden's 2nd Edition is a fully updated, new book (as of late fall 2016) with an excellent up-to-date discussion of modern cosmology including the basic Friedmann-Robertson-Walker frame-work. However, it does not address all relevant aspects of observational cosmology, which is why I suggest that we may use Longair's book as complementary source of material. The important parts to fetch from Ryden's book are chapter 3-10, which provide a more modern framework of Lambda-dominated and equation-of-state cosmologies. If you take this course for a grade, you need to get and read Ryden's book.
