A Martian is a native inhabitant of the planet Mars.
 Although the search for evidence of life on Mars continues, many science fiction writers have imagined what extraterrestrial life on Mars might be like.
 Some writers also use the word "Martian" to describe a human colonist on Mars.
Price Stern Sloan (originally known as Price/Stern/Sloan) or PSS!
 is a publisher (now an imprint of the Penguin Group) that was founded in Los Angeles in the early 1960s to publish the Mad Libs that Roger Price and Leonard Stern had concocted during their stint as writers for "Tonight Starring Steve Allen" and also the "Droodles".
 Along with their partner Larry Sloan, they expanded the company into children's books, novelty formats, and humor.
 Some of the books they publish include movie tie-ins for films such as "Happy Feet", "Wallace and Gromit", "Catwoman", and "Elf", "How to Be a Jewish Mother" (1964), "Jack S. Margolis' Complete Book of Recreational Drugs" (1978) and other properties such as "Serendipity", "Mr. Men" and "Little Miss", "Wee Sing", "Baby Loves Jazz", and books by children's artist and designer Salina Yoon.
 Today, PSS!
 still publishes approximately ten Mad Libs books a year.
 Mr. Stern and Mr. Sloan went on to found Tallfellow Press in Los Angeles.

According to Tatin Yang in the article "Romansang Pinoy: A day with Tagalog romance novels", Tagalog romance paperbacks were thin Philippine versions of romance novel books that could be found at the bottom shelves of the romance section of bookstores, wrapped and bound with book covers that are decorated with Philippine comics-styled illustrations, such as "a barrio landscape with a badly dressed guy and girl locked in an embrace".
 As a form of "escapist fiction" (escapism) and "commercial literature", Tagalog romance novels generally follow a "strict romance formula", meaning the narratives have happy endings (a factor influencing the salability of the novel), the protagonists are wealthy, good-looking, smart, and characters that cannot die.
 Normally, the hero or heroine of the story falls in love and "goes crazy" over the admired person.
 However, later authors of Tagalog romance novels deviated from portraying so-called "damsel-in-distress and knight-in-shining-armor characters".
 Contemporary writers also turned away from writing "rags-to-riches plots".
 The stereotypical norm had been replaced by the incorporation of storylines with "interesting scenes, characters [who are ready to face challenges or to sacrifice themselves for the benefit of other people], dialogues, and new angles to old plots".
 Authors such as Maria Teresa Cruz San Diego, who used the pen names Maia Jose and Tisha Nicole, ventured into the fantasy romance genre, and into topics that are related to politics, ecology, gender issues, prostitution, mail-order bride syndicates, white slavery, non-governmental organizations, and breastfeeding programs.
 Apart from writing about ideal lovers (men and women) and ideal situations, other novelists wrote about true-to-life settings, or at least based the stories from personal experiences.
 Thus, Tagalog romance novels came to mirror or replicate the "roles that women and men play" in Philippine society.
