I am interested in elementary algebra texts and/or notes that place early and continuous emphasis on universal constructions, functors and other aspects of category theory. One text that takes this approach is Aluffi's Algebra: Chapter 0.
Another text that emphasizes universal constructions early-on is Hu's Elements of Modern Algebra
Are there other elementary algebra texts and/or notes that integrate universal constructions and principles of category theory into the development of the subject?
