The Internet Library of Early Journals is an interesting site of older newspapers from Great Britain and is a project developed by the Universities of Birmingham, Leeds, Manchester and Oxford. Its goal was to digitize substantial runs of 18th and 19th century journals and was first completed in 1999. No new material has been added since. The collection includes runs of at least 20 consecutive years of the following journals: Gentleman's Magazine, The Annual Register, Philosophical Transactions of the Royal Society, Notes and Queries, The Builder and Blackwood's Edinburgh Magazine.
There's not a great deal of genealogical information here but interesting reading none the less.
