Logos Bible Software
You really have to just visit their website to see what Logos is about. https://www.logos.com/To buy the whole thing is quite pricey - but lucky for me I was a very early adopter - when it was still called 'libronix' and I bought my first package on a sale at Scripture Union years ago - when it still came in CD form.
Mostly I use the NRSV with Greek and Hebrew parallels.
I find the Anchor Bible Dictionary very useful.
And the IVP Bible Background commentaries and dictionaries.
Kindle
Kindle is really useful for preaching prep. I am frustrated by not being able to lend people my books - but I'm also pleased that I'm not constantly losing books. Best thing is I can make the most of any moment. Kindle on my phone, iPad, PC, and Kindle means I can highlight and annotate wherever I am and those highlights are available when I check in to my PC.Duet App
It is great to be able to connect in a second screen via USB through the Duet App. Running books, libraries etc. all on one computer I can easily glance from left to right at all my windows.This is also helpful when planning worship - I set up the presentation program on one screen and keep all the order of service lists etc. on the other side.
