I have borat123 and was a pretty good read, gave me some extra confidence that I was on a reasonable path as I already more or less roasted that way. Combination of learning off Mark Beattie from Coffee Roasters Australia, Coffee Shrub crew (turning point in my roasting style chatting with these guys), Kees Kraakman stuff (more great reading) and doing a Boot Camp Coffee course. Also throw in all the great info shared online from guys like BeanFlying and KK early in the journey. Add in the few hundred kilos of roasted mulch in my garden beds ;D and that's my coffee roasting journey to date, still plenty to learn and understanding the nuances of all the coffees out their and how seasonally they can change is a huge endeavour and most enjoyable.
