I’m a pretty avid reader, at one point having a huge collection of paperbacks and hard covers which I ended up donating to the local public library when the books started taking up too much space in our NYC apartment. Since then I’ve been buying primarily ebooks through Amazon Kindle, already surpassing 500 titles there. This category contains just a couple of sci-fi authors who have written so many titles that I wanted to keep a list of their many books so I don’t end up buying titles I’ve already read.
