A word about the Webinars: The new webinars: (http://www.accordancebible.com/support/webinars.php) Just this year, Accordance Bible Software started offering web-based seminars focused on a single topic, like basic searching, how to use particular resources like the new ESV Study Bible, how to use Strong’s numbers, and most recently, how to search in Greek.
The webinars are taught by Dr. Timothy Jenney (Dr. J for short), who has a real gift for pacing and making things easy to understand. At this point, only a handful of people seem to be signing up for the webinars (most download the recorded sessions later). The 1:00 pm session usually has an especially good teacher to student ratio. That enables you to get specific questions answered that you might hesitate to ask in a live seminar.

It is also worth mentioning that if you have a PC, you can run Accordance Bible Software through an emulator and it works very well.
