Here's a few Martian titles that seem to have fallen through the lines...
SF:
Frontera - Lewis Shiner
Red Dust - Paul McAuley
Mars Underground - William K. Hartmann (yeah, the very same)
Desolation Road - Ian MacDonald
Fantasy:
the Kane series by Michael Moorcock
the Stark adventures by Leigh Brackett
On the science front:
Mariner IV to Mars - Willy Ley
Mars - Robert Richardson & (the great) Chesley Bonestell
Beagle - Colin Pillinger
Destination Mars - Martin Caidin
plus books by Kargel, Boyce, Hartmann, et al.
One of these days I must get my martian library organised... It includes books in english, french, italian, spanish and portuguese.
And I leave you with a fine piece of martian poetry, by Richard L. Poss:
For years I wandered
the Martian landscape.
The infinite varieties
of silence
kept me company.
