Exporting your library from Visual Bookshelf in Facebook (or LivingSocial: Books) to Readernaut

1. Link your Visual Bookshelf Facebook account to an external LivingSocial: Books account (relevant Visual Bookshelf FAQ entry)
2. From your LivingSocial.com account, choose Manage, and look for the Export to CSV link near the bottom of the page. (VB FAQ)
3. Replace all instances of ^.+?","([\dX]{10}).+$ with \1 using TextWrangler/other text editor with grep(-like) find and replace
4. Copy resulting list of ISBNs into Readernaut
5. Feel good about having a Readernaut account in the first place

N.B. I have no 13-digit ISBNs in my reading list so it’s really not my problem.
