From time to time publishing houses decide, for commercial purposes, to revive long-forgotten authors and reprint one or two of their more commercially successful novels. Apart from Penguin Books, who for this purpose have resorted to their old green cover and dug out some of their vintage authors, Pan started a series in 1999 entitled "Pan Classic Crime," which includes a handful of novels by Eric Ambler, but also American Hillary Waugh's "Last Seen Wearing ...". In 2000, Edinburgh-based Canongate Books started a series called "Canongate Crime Classics," —both a whodunnit and a "roman noir" about amnesia and insanity—and other novels. However, books brought out by smaller publishers like Canongate Books are usually not stocked by the larger bookshops and overseas booksellers. The British Library has also (since 2012) starting republishing "lost" crime classics, with the collection referred to on their website as "British Library Crime Classics series".
