I made an attempt to move over to ebooks a few years ago, mainly in the hope of realising some more space (I literally have hundreds of physical books, many from when I was an academic).
However, over time, I’ve realised that I really prefer physical ones (except for travel). I was curious why this was so and Michael Hyatt has given 8 reasons:
1. Ebooks Are out of Sight and out of Mind
2. Ebooks Engage Fewer Senses
3. Ebooks Make It Easier to Get Distracted
4. Ebooks Result in Less Retention and Comprehension
5. Ebooks Feel Too Much like Online Reading
6. Ebooks Are More Difficult to Interact With
7. Ebooks Are More Difficult to Navigate
8. Ebooks Provide Less Satisfaction in Finishing
My current approach is to read a new physical book through a local library (which also helps keep it going, so that’s a win-win) to see how good it is. If they don’t have it in stock it’s easy and cheap to request it (even for quite technical books eg through inter-library loans). In fact through the British Library you have access to most books that have been published (at least in the UK).
I’ve found in practice that having my own copy is now not that important and I now only buy a few ‘exceptional’ ones (ie ones that have a large and lasting impact on me).
However, I wonder if this is also generational. I was brought up on physical books but for someone brought up on ebooks (and digital media in general) it might be quite different.
