A construction of the quantum affine algebra U q (Δ) is given in two steps. We explain how to obtain the algebra from its positive Borel subalgebra U q (b + ), using a construction similar to Drinfeld's quantum double. Then we show how the positive Borel subalgebra can be constructed with quantum sh
