I used to make a living at the lithographic process as a camera operator at
my hometown newspaper. Lithographic films and papers are a special high
contrast copy material and the lith developer brings out the nearly two
tone results that people know as litho. The lith developer results in a
loss of film speed on anything it's used on, so testing should be done to
determine what you will get out of it. The best results are had with
materials that are already high contrast such as single grade high contrast
papers and lith materials. The highest contrast can be had by printing onto
lith film and then contact printing to another piece of film or paper
depending on the results desired.  A form of bas relief can be achieved by
contacting positives made with a short and a long exposure on film and
swapping pos and negs from the two, aligning and contacting the set to
paper. Experimentation is mandatory and quite fun at this point. 
Nowadays you can also get these effects with any scanned image by
converting to B&W and the reducing the bit level until it looks interesting
enough. The effect is in theory the same as what litho film does to an
image but asthetically not the same in appearance most of the time. 
Litho developer can be had in a liquid concentrate that comes in two parts
and unmixed lasts an incredibly long time. If you find you don't like
playing with it you can save it and pass it on later to a friend or try it
again on another image when you get bored.
