In 1996, W L Bentley Books published Volumes 8 & 9 of Horace Traubel’s With Walt Whitman in Camden. These final two volumes in the series are still in-print. My original website about Traubel’s nine-volume series, with a full bibliographic history of every volume and sample extracts from Vols. 8 & 9, is still online here:
It is very likely that an e-book version of Voumes 8 & 9 will soon be available for download and purchase as well.
Both books are available from me through Amazon here. But I can still supply new copies of Volumes 8 & 9 directly. to arrange for payment and shipping.
