For those interested in making corrections to information in your copy of First Aid for the USMLE Step 1 2012, the official FA errata is now posted to the FirstAidTeam.com website. You can check out the webpage to learn more about the process, or RSS subscribe for updates. If you’d like to bypass the site and just go straight to the errata, the document can be found here (pdf).
Keep in mind that you can send in a correction for any mistake you find by clicking on the “Contribute” button on the right side of their site or this post (both bring you to the same place on their site). While they promise $20 Amazon gift cards for new information, someone else has probably already beaten you to any given correction. Nonetheless, making any submission will get your name printed in the preceding version of Step 1.
