The Scotsman has launched a digital archive of 19th century material - every issue of the newspaper from its first publication in 1817 up to 1900.
As part of its 150th anniversary The Age recently published a similar, albeit less ambitious, site. The Age has digitised a selection of its archival material going back to 1854.
The attractions are obvious, as is the educational potential. But for anyone with even a passing interest in history these archives are a great tool.
