A book series might be as little as two novels or as much as 50 books and counting. It all depends on the sort of narrative you're telling and how long you take to tell it. A series is just another way of organizing books so that you can find them in order.
There are several different types of series: alternate history, anthology, action/adventure, fantasy, science fiction, children's, graphic novel, prequel, sequel, and spin-off.
An alternate history series tells stories where history differs from what actually happened. For example, one could imagine what would have happened in America if George Washington had failed to win our first American Revolution. Or one could look at global events after World War II ended differently if Stalin had lived longer. The possibilities are endless!
In an anthology series, each story or collection of stories is written by a different author. Examples include the Dark Tower series and The Lord of the Rings series.
In an action/adventure series, the stories feature characters who go on adventures that include fighting bad guys. Readers love seeing pictures of cool weapons and vehicles so they can pretend they own them too! Example titles include The Harry Potter series, The Hunger Games series, and The Mortal Instruments series.
The distinction between writing a trilogy and writing a series of books is that a trilogy is one continuous plot arc. A series of novels can be whole stories set in the same setting and with the same people. They just tend to be more self-contained.
Triology is an ancient Greek word for "three things." It may also refer to any narrative composed of three parts, or chapters. The term is most commonly applied to literary works consisting of three connected poems, or hymns. These are called trilogies by some scholars because each poem usually has a similar theme or argument and contains many similarities of language and structure. The terms "trilogy" or "triple play" are also used for other combinations of poems or songs.
Books that have been called trilogies include: Homer's Iliad and Odyssey; Virgil's Aeneid; Goethe's Faust; Dostoyevsky's Crime and Punishment; Thomas Hardy's Wessex Series; James Joyce's Dublin Trilogy; John Updike's Rabbit Angstrom Books; J. K. Rowling's Harry Potter series.
Series consist of a group of two or more related books that deal with the same or overlapping characters from different points of view.
A trilogy is a three-book series in which a tale is told in three sections. Each section can be read as a stand-alone story, but understanding of the overall plot requires reading all three parts in order.
Triology is a term used to describe any work of literature that is divided into three parts, such as a novel, a play, or an album. The opposite of a trilogy is a single-volume work; for example, a collection of short stories would not be called a trilogy because it contains only one narrative.
Trilogy is a common term used to describe any work of fiction composed of three parts, as in "a three-part poem." However, this usage is rare today. When used in this way, the word "trilogy" is often followed by the name of a specific work, such as "the Tristesse du Roi," "the Three Musketeers," or "The Lord of the Rings."
Often, but not always, these works are written by the same author or group of authors. Sometimes two different writers will each write a part of the trilogy, and others will join them later for the completion of the story.
This is, however, a rare occurrence. Some book series have been referred to as "quintets," however this is usually when the volumes are about a musical tale. A series is a collection of five or more novels, often known as a sequence or a collection. When a series is tied together, it is referred to as a "omnibus."
A series of paintings by a single artist is called a "sequence." A series of events that occur one after another is a "run." A series of articles or essays on a subject is called a "series."
In music, a quintet is a group of five instruments. This arrangement of instruments is common in classical music, but also appears in jazz. In addition, there are other groupings of instruments such as trios (three instruments) and quartets (four instruments). These terms do not apply to ensembles that include more than five musicians; for example, a sextet includes six instruments.
The term "series" can also be used for collections of works by the same author or painter. For example, George Bernard Shaw wrote several series of plays: one about women, one about men, one about love, and so on.
For example, the Beatles are considered a series because they were a group who had many successful albums over a relatively short period of time.
