Jonathan Ross has contributed an article about Victorian stereo photographer Michael Burr, to The Stereosite.

"Michael Burr was one of the most prolific photographers of staged genre stereoviews in the Victorian era. Following in the footsteps of masters like James Elliott and Alfred Silvester and frequently adapting the themes of other popular photographers, this Birmingham based entrepreneur created a catalogue estimated at over 1,000 images during a period from 1862  to the mid 1870s and evidently sold his work in large quantities as there are so many of his stereoviews still surviving."........
