I have just finished the best of Eric Frank Russell enjoyable stuff Russell was a British writer who was a mainstay of the SF magazine Astounding in the 1940's and 50's and it is a good introduction to his work. I also finished the Moons of Jupiter the 5th of Isaac Asimov's Space Ranger series (written for teenagers). The book I am reading at the moment is They Shall Have Stars the first volume of James Blish Cities in Flight series. Now I could get this for the Kindle (as an omnibus edition) but as I have all 4 volumes in paperback.... about 30 pages in and very promising 1950's SF.
I don't expect this trend for physical to continue I am just clearing up a few books I have not got a round to over the years that I now have the urge to read and not sure how long it'll take.
I have to say I am enjoying going back to 1940-50's SF. It is amusing to read these views of the future, they envision flights to other planets but not touch screens. There is blatant sexism, the little woman etc etc which modern readers will find jarring but these are stories of there time. Often they lack the writing skills of modern writers but they have an energy and economy of pages that modern writers lack. They tell a good story.
