Kindle loc refers to the "location" or "location guide" on the Kindle device, which has no exact meaning. In Kindle e-books, text is marked by "location" instead of page numbers or chapters. Because different devices have different screen sizes, even if two devices display the same book, their position guidance is different. So on the Kindle, the location guide provided is a relative value, which shows the number of words and letters you read in a book.

Kindle loc can also be used for book citation. People can use Kindle loc to indicate the location of references, which will make it easier to find and quote references in the future. Most academic papers and magazines allow Kindle loc as a citation position, which can greatly reduce the trouble of searching the book catalogue and page number.

Although Kindle loc has no fixed meaning, it is a very convenient way to read the label. The advantage of this method is that readers can jump to a certain position in the book without turning pages or scrolling. In addition, the concept of Kindle loc is also applied to Kindle applications, because it can save the location guidance of Kindle e-books in the cloud and allow multiple devices to synchronize reading progress.
