Contrary to the oft-uttered phrase, you can likely tell a lot about the book you’re picking up based on the cover. For one thing, you might be able to guess at the genre. You may also have some idea of when the book was published. Over the last fifty years or so, book cover art has changed a lot. This is true across a wide mix of genres. A few years ago, we published a retrospective on the evolution of romance cover art. With the recent news that mass market paperbacks are facing extinction, we've decided to look into the cover art evolution of a few more of our favorite genres.
We recently published a post about the cover evolution of fantasy novels and we want to acknowledge that the lines between science fiction and fantasy can be a bit blurry. There's some natural crossover between the two genres. But generally speaking, science fiction explores possibilities that are rooted in science and technology, while fantasy explores supernatural, mythical, and other worldly scenarios.
Modern science fiction emerged in the nineteenth century, with Mary Shelley's Frankenstein (1818) often cited as the first true work of the genre. It was followed by the pioneering technological tales like Twenty Thousand Leagues Under the Sea by Jules Verne (1869) and The Time Machine by H. G. Wells (1895). Interest in science fiction grew during the early twentieth century as expanding technologies opened humanity's minds to new possibilities. As the Space Age took hold in the mid-1900s, the genre exploded into mainstream popularity with the innovative works of authors like Isaac Asimov and Robert Heinlein.
In 1939, Robert DeGraff launched pocket books, small, cheaply produced paperbacks that were easy to take everywhere. This was a game changer for the evolution of book covers.
With the popularity of these lightweight, inexpensive volumes, a book's cover became a critical selling point. Publishing houses began investing heavily in art that would stand out on the crowded racks of paperbacks for sale at corner stores, magazine stands, and airports.
This was an era of massive social change. As the culture shifted toward the experimentation and exploration of the hippie counterculture, art followed suit. Sci-fi cover art sported bright colors, digitalized lettering, and trip-tastic alien lifeforms.
Here are some stellar examples of covers from this era:
The Star Wars franchise was launched in 1977, firmly entrenching speculative entertainment into the mainstream media landscape. During the boom that followed—sometimes called "The Star Wars Shift"—the cover art of science-fiction novels took on a higher level of realistic detail.
This era of science fiction saw shifts toward climate fears, murderous alien invaders, and isolation. Popular sci-fi covers of the time gravitated toward dark, dramatic scenes involving interstellar battles, gritty dystopian landscapes, and cyberpunk. With computer technology advancing rapidly during this time, robots and androids are another common feature of these covers. In the 1990s, as technology advances like the internet changed every aspect of our lives, there was a notable shift toward brighter colors and a more optimistic feel for science fiction covers.
Starting in the late 1970s, Octavia Butler revolutionized the science fiction world with her Afrofuturistic and feminist novels. So the original 1987 cover of Dawn, the first book in her Xenogenesis series, must have been quite jarring to the author. The cover shows a white woman unconscious as another woman, also white, stands over her. This image doesn't line up with the book's story of Lilith Iyapo, a black woman who is one of the few humans to survive Earth’s self-destruction after being rescued by an alien species.
A decade later, Butler's new publishing team spearheaded a comprehensive redesign of her covers, many of which had previously misrepresented her characters as white. Artist John Jude Palencar created artwork that matched Butler's descriptions, giving new life to her groundbreaking novels. His gorgeous 1997 cover of Dawn is one of our favorites from these efforts.
Here are some of the cover designs that have impressed us over the last several decades. As you can see, these stunning covers run the gamut from renaissance-style frescoes to painterly futuristic cityscapes to photorealistic spaceships. As with the other genres we've been covering, the current era of online shopping and eBooks has ushered in simpler, stylistic cover designs, sharp color contrasts, and larger text so that titles and images read in a digital format.
We’ve had a blast unpacking the details of the mystery cover evolution. If you enjoyed this, be sure to check out our previous cover evolution posts for fantasy and mystery.
