There are basically two types of sleeping bags. One is the mummy bag and the other is the "old school" rectangular sleeping bag. Now mind you, ain't nothing wrong with old school at all. In fact, it may be your preference once you discover what it's like verses the mummy bag.
Rectangular shaped bags are the most popular and most familiar. These provide you with more room for movement within, reducing that claustrophobic feel to some degree. Because they are of a square shape they can also be zipped to a second to produce a double sized sleeping bag, large enough for two people to sleep in. Or, if you completely dislike the feel of being zipped up, you can leave the bag unzipped entirely and use it as a blanket instead. However, these bags are often fairly big, and may not be ideal for hiking trips as they can be rather bulky and awkward to carry.
In 1917 the zipper was perfected and, of course, these made for a great seal for the rectangular sleeping bags allowing a persons body heat to stay trapped longer therefore keeping them warmer on those cold winter nights. Basically the term sleeping bag essentially means a protective bag for someone to sleep in. and is basically two blankets that can be zipped together in cases where a bed is not available. There are a couple different shapes of bags outlined below.
