Where Are the Readers?

I am sitting at a craft fair at one of the top schools in our city trying to sell my books. The visual aversion people have to books is remarkable. I bet that 2/3 of the people I have offered a free bookmark to have refused. 

Where have all the readers gone? I offer historical fiction, memoir and non-fiction.  The most interest is in a cookbook series I created from my Mom’s recipes. The intrigue is in the fact that I scanned in her recipe cards but no buyers.

I self-publish my books and thought that Arts & craft fairs would be a good venue for selling–especially at a school,  it I had a similar experience last year at the top school here. 

Any suggestions?
