Step back in time at library

Library visitors will be able to step back into Perth's history from today, thanks to a green screen and a vast pictorial collection.

For the National Trust's heritage festival, the State Library is helping people "travel back in time" by being photographed in front of historic and significant moments in the history of Perth.

Today you can march in an anti-Vietnam War protest on the foreshore in 1972 and tomorrow be in the chorus at the Princess Picture Theatre at Cottesloe beach.

On Thursday, join the 20,000 people who watched legendary aviator Bert Hinkler fly over Perth Oval in 1928.

On Saturday, you can be there when Perth's streets were lit up for Armistice Day on November 11, 1918.

"The library has a huge collection of photographs, many of which are undiscovered or unexplored," acting director, community, learning and discovery, Elizabeth Spencer said.

"While much of our collection can be used for the purpose of historical research, thousands of digitised images can also be used creatively and for 'mash-ups'."

The photos are being taken at the library between 1.30pm and 3.30pm each day.
