The National Library of Scotland and the Glasgow Film Theatre will showcase some rare films on Tuesday as part of UNESCO's World Day for Audiovisual Heritage.

The library (pictured) will show some of the material from its Scottish Screen Archive. The footage to be shown includes restored film of the earliest known personal wedding film in the UK, held in 1905.

Two other films that will be featured include a tram ride round Rothesay Bay in 1909 and entertainer Sir Harry Lauder's visit to a Glasgow cinema in 1928.

The National Library is also set to unveil the first phase in its programme to digitise complete films for online presentation from the thousands of materials within the Scottish Screen Archive catalogue. Around 100 films will be available to view online in the next few weeks as part of this programme.

Janet McBain, curator of the Scottish Screen Archive at the National Library of Scotland, said: "Our conservation work ensures old and often damaged film can be made available for future generations to enjoy when otherwise they may have been lost forever.

"For example, our footage of the earliest known wedding film of the 4th Marquess of Bute to Miss Augusta Bellingham, which will be showcased in our new visitor facilities for World Audiovisual Heritage Day, took our dedicated team over three years to restore and produce for public view.

"Also, we are now in the first phase of our online digitisation programme that will enable even more people to enjoy footage from our archives through the website.

"The films we have begun transferring to online format are to reflect the topics most requested via the NLS website such as how we used to live, family history and transport and travel, to name but a few.

"Therefore this day is a fantastic opportunity to not only reveal some hidden audiovisual gems but also highlight the great care that goes into preserving material for public display."
