Bookstore Browsing

Recently I visited a large retail bookstore near my home and was struck by some of the oddly specific category labels above the bookcases. No need to go digging around a massive Computer section for a book on Photoshop — you can go straight to Digital Photography. Looking for the latest young adult vampire novel? There's a Teen Paranormal Romance section for that.

The bookstore employees must have thought I was strange or terribly indecisive as I wandered through the whole store with my iPhone taking note of the various genres and the number of bookcases devoted to each. I was curious — in a time when we get so much of our entertainment and information digitally, what do we buy in bookstores?

At first glance it looks like children's books, various fiction genres and cookbooks. But the real answer probably doesn't appear on this chart. If you've visited a chain retail bookstore lately, you know a significant amount of floorspace is devoted to CDs, movies, e-readers, board games, toys, gifts — things that aren't books at all. I've left most of those items out of the chart simply because the various racks, tables and shelves used to display them are difficult to compare to the standard bookcases. The massive "Bargain" section, which certainly includes some non-book items, is shown here.

I've used data from a bookstore in Fairfax, Va., a suburb of Washington, D.C., where the demographics include a lot of affluent, educated and professional families with children. I'm curious to see how the inventories of bookstores in other parts of the country stack up.

My first attempt with this data was a bar chart:

I spent a few days on this bar chart — one day on the admittedly unnecessary bookcase icon and the rest adjusting the bar size and trying to shoehorn in the category labels in a semi-legible manner. Success was mixed. My lesson here is that if one approach doesn't seem to be working, it's probably not the right approach. After about 30 minutes of reformatting my data spreadsheet to Google's liking, Google created the "tree map" at the top of the page in a few moments.
