微出版是个人或团体使用便捷的出版和信息技术，用来发行于特定分众市场的工作。由于过去几年微出版的发行收益较小且经济规模无巨大表现，此类型的出版方式往往不为传统的纸本出版商所理解与接受。

在互联网互连网的出现之前，微出版仅仅被认为是一个“微趋势”，出版界从来不当一回事；伴随着互联网改变了所有终端的消费模式，微出版先逐渐被美国出版界所接受，成为作者与网络出版商之间人人可以负担得起的出版和发行新媒介。

互联网不断地发展，从传统的出版到现在微出版事业的启蒙，作者与网络出版商也随着数字内容与收益金额逐渐成为正比而获得信心。对于微出版的数字内容，普及全球的读者群与网络跨越国界的大环境，刺激了更多有文才的作者得以愿意进入微出版业。
