Hmmmmm
I enjoyed Dr Kate Leeming "Out There And Back"

in the introduction to the above, she writes about her traverse of Russia.
Whilst she didn't write a book on that journey, her cycling companion Gregory Yeoman did in his "Riding into the Sunrise" which I also enjoyed as a yarn.

Oh and Kate has a second book which I've yet to read which was about her African Expedition called "Njinga"

You can get an idea of what she's about from her website:

I found a lot of touring inspiration reading GJ Coops work which some can be found:
cycle trails Australia: Cape York, Qld and some within the site mentioned below
As mentioned in a post above in posts 4 and 5, lots of work from cycle tourists at the Crazy Guy On A Bike site which would keep you busy for many hours reading till the wee hours
