Ask HN: My company will buy me books. What should I get?

My boss and I recently had a 1-on-1 meeting where he told me that if I ever wanted any "training" to let him know, and he'd try to work it out. It didn't have to be directly related to my line of work (marketing/social media).

I found http://hn-books.com/ here a few days ago and I've pulled about 5 books off of there, but I'm looking for more!

The fields I'm looking into:

-Marketing/Messaging/Reading people

-Programming (specifically Perl. I have a year of a CS degree behind me, and I've worked with Perl on and off a lot on my own and looking at using it a lot more.

-Excel/databases (I just discovered Pivot Tables in excel and I'd love to learn more about them. In addition to that, learning the basics of how to set up and use simple databases)

-Data Analysis (If Excel/databases is the technical side, then also more the "soft" side. Things to look for, ways to improve your analysis skills, etc)

The books I currently have on my list are: Art of SEO, Art of Speedreading (People), Learning Perl, Word of Mouth Marketing.
