If your wondering how much commitment would be required before commiting to the reading plan then this is a link to an online version of the Beveridge edition:

These will help give you an idea of how much reading is scheduled for each day – normally about 3 pages. I read the first day’s section the other day and it took 7 minutes to read. However, understanding it is another issue!!

Princeton Theological Seminary is also encouraging readers to read through the Institutes in 2009. One thing that Princeton provides is the audio readings from the McNeill/Battles translation of 1960. You can subscribe to the clips via a podcast.
