Book Crawler v5.2.1 released and available for download at the App Store!  Please update for the latest enhancements and features and (like with all of our releases), we really appreciate your updated App Store reviews.  UPDATE: We are aware of the ISBN scanner auto focus issue and have already corrected it.  The fix will be released in the forthcoming BC v.5.2.2 very soon!  Please pardon our dust as we continue to develop the very best book database application available at the App Store! Thanks!
