 ## Sparsity
 
+!!! tip
+    If you use DifferentiationInterface's Sparse AD functionality in your research,
+    please cite our preprint [*Sparser, Better, Faster, Stronger: Efficient Automatic Differentiation for Sparse Jacobians and Hessians*](https://arxiv.org/abs/2501.17737).
+
 Sparse AD is very useful when Jacobian or Hessian matrices have a lot of zeros.
 So let us write functions that satisfy this property.
