Have been reading, for the first time, Mike Resnick's four-volume "Widowmaker" series over the past few days. It's entertaining, basically a space western as most of it takes place in the author's vast Inner Frontier setting.
But volume three, "The Widowmaker Unleashed", deserves special mention for revealing an interesting quirk of the title character: along with banking much of his bounty money for his old age/retirement (a chronic health issue changes his plans and triggers the events that are the series), the man has stashes of real paper books (he doesn't like "reading pixels") stored on various planets which he plans to send for once he settles down so he can spend his time reading them (along with gardening and birdwatching). When he buys his first house, planning to live out his remaining years there, one of the priority renovations is building bookshelves in anticipation of his collection arriving. It's impossible for me not to love a fictitious character who does that. :-)
