Many stereograph collections have been digitized and are now available online. The means to view them in stereo however may not be readily available for a general audience. Working with some filename modifications, the Stereogranimator website from NYPL Labs, and a handful of different smartphone apps, viewing stereographs digitally in three dimensions is now possible. Students of visual materials, the history of photography, and other online researchers can now view the stereographs as the medium was originally intended to be viewed.
