I use a free program called Calibre to manage all my ebooks. Not only does it manage my ebooks, but I also use it to store my reviews offline so I’m not dependent on the internet. The developer is a fantastic guy from India who is active, my age and has been going since 2008 or so. Which means there is very little chance of the program just suddenly stopping (barring him dying of course). Even then, I could export everything into a csv file and export it into a spreadsheet, so I’m covered even that way.
Not only does Kovid Goyal maintain the program, but it is open sourced and a lot of other fantastic people have written plugins that can enhance what Calibre can do. I use several plugins, one of them being the Page/Word count plugin. I’ve only been using the Page Count part of the plugin, to keep my numbers consistent but since I decided to start keeping track of words as well, I was using a combination of Kobo.com and Readinglength.com, completely forgetting that the second half of the Page Count Plugin was for WORDS.
Now there will be some internal consistency to my page and word count numbers. I highly doubt any of you will notice a change in my reviews but this is mainly for me anyway. Instead of some of the highly questionable “guestimates” based on audiobook length, etc, etc, I will have the same formula so when I compare Book A to Book B they are using the same metric and it has actual meaning. That “means” something to me, hahahaha.
If you use ebooks a lot, I highly recommend Calibre. It has its own Support Forum on Mobileread which is a great place, barring one person from Massachusetts. Don’t expect to babied along and spoon fed though. You are expected to have done your own homework and to DO the work yourself. I lurked there for years before joining and learned alot. I still visit daily just to keep up. It is amazing what people can do with Calibre, even while I have no need of whatever it is they are doing.
I guess this was just a huge Calibre plug (in), hahahahaa. But I tell you, I use it so much that I’ve donated to show my appreciation. Free program, free help (and let me tell you, sometimes the threads for help get wicked involved and go on for pages and pages), and it does what I want it to. I couldn’t ask for more.
If you have any curiosity or need, go lurk at the forums and see. However, the best way to learn about Calibre is to USE Calibre.
