For the Antiquarians--the online works of William Morris. Arguably a better poet and designer than prose artist. Nevertheless, once you slip into the oddities of style, there is something wonderful about William Morris's work. Definitely for the medievalists and pseudo-medievalists amongst us. Waters of the Wondrous Isles, translations of Old French Romances and Icelandic sagas, and some very, very, very fine poetry.
And for those more modern, a relatively early work by Andre Norton.
