I'm not sure I have accosted strangers in the street over this book, but I must confess to recommending it whenever I can:
Charles Dickens: The Uncommercial Traveller
It's a collection of short social reportages, showing off Dickens as a reporter, rather than a novelist or author, and throwing quite a lot of light over Victorian England, some amusing, some nostalgic, and some as scathingly critical as anything by a modern writer.
Don't read the first story: The Shipwreck: it's Dickens as his most pathetical, and feels quite a bit tacky today -- at least to me. But already the next (Wapping Workhouse) is a decided improvement. The one everyone should read who read Dickens is number 8: The Great Tasmania's Cargo.
The ghost stories of M. R. James are also favourites: short enough to be read in one go, and long enough to be interesting.
Look for these texts at the Online Books pages:
http://digital.library.upenn.edu/books/. I prefer reading them in printed form, but I expect the iLiad or the Sony will alter that.
(I see that
www.eserver.org is not listed as a source of the Dickens text ... you'll find it there, too.)
