Looking around on the internet the other day, I came across the page for the Scottish Life Archive, which seems to have had a bit of a facelift since the last time I visited the website.
The archive has been around since the 1950s and aims to collect, record and preserve documentary and illustrative evidence of Scotland's material culture and social history.
They have built up a fascinating collection of material that could be useful for anyone researching aspects of Scottish local or family history and you can get a taste of what they have by visiting their website, and you can view images of some of their photographic collections on flickr.
Viewing the collections is by appointment only (see their website for contact details), as well as holding photographic and film material the Scottish Life Archive is home to a unique collection of manuscripts, letters, diaries, books, leaflets, oral recordings, maps, plans, trade catalogues, paper ephemera and an extensive newspaper cuttings collection.
If you're searching for details about a particular person, place or theme, then it might well be worth a visit.
