books about the book publishing industry

I am looking for a book about the book publishing industry. Eventually I want to get a job at Random House or similar, but first I need to do major research before I approach them or any similar company.

Preferably about the things that are current issues, or future issues, or anything that would be important for me to know before taking a job in that industry.

Links/online articles are acceptable as well.

Thanks in advance :),
