As the previous discussion has revealed, there are many available resources from which to seek historical mathematical images for instructional purposes, and I have suggested some techniques for their classroom introduction. We all have our personal collection of mathematics texts and reference books that can supply us with images. Library searches, especially among large university holdings, also prove fruitful; however, computer searches of existing digital collections similarly provide many visual treasures. A listing of some available sites appears below. In such search efforts, one must be mindful to comply with all legal and/or cost requirements attached to items.

However, the Mathematical Association of America, MAA, has compiled an archive of historical images specifically intended for instructional purposes that is available to all mathematics teachers and researchers free of cost. It is found online in the Association’s electronic journal *Convergence* as the feature “Mathematical Treasures.” The majority of images discussed here, together with over a thousand others, are available for use from “Mathematical Treasures.” I sincerely hope that many readers of this article will avail themselves of this wonderful resource.
