I am familiar with some of the popular scanning software for the Windows environment and most of the scanning market as well as the awards for acuracy goes to Nuance's product called Omni Page,
http://www.nuance.com/for-individual...page/index.htm. There are free and less expensive OCR software available but since you are dealing with a particularly dificult job to do I would recommend the best of the OCRs for the job. If you told forum members that you are scanning simple harback books with no graphics then i would suggest a trip to Sourceforge to find software for the job.
