There are a number of really informative books on bicycle frame geometries, some of the more radical stuff and
the building process.
I would recommend these somewhat rare guides:
Sharpe's Treatise on Bicycles and Tricycles (originally published in the l890's) The basic principles hold today.
The CONI(Olympic training manual) (1972) When the philosophy and physiology merge.
Designing and building Your own frameset - Talbot Good overall guide and advice
Speaking of radical - check out the book by Chris Boardman.
Not real rare:
Lugged Frame Construction - Chimonas
And, as written earlier:
The Proteus Manual - more on the builder side Proteus bicycle company sold builders supplies
Custom Bicycle
