Recommendations for good cosmology books include Dodelson's "Modern Cosmology," which is ideal for third-year undergraduates, and Liddle's book, noted for its comprehensive coverage despite being slightly dated. Another suggested title is a well-written book that, while thorough, may not be suitable for beginners. Additionally, a book focusing on structure formation in cosmology is mentioned as a good resource. Lastly, "Primordial Cosmology" by Peter and Uzan is highlighted as a very new and valuable addition to the field.
