What is the most productive way to keep yourself engaged while traveling or commuting to and from work? Reading a book! Even though the habit has remained the same, the mode of consumption of the written content has changed drastically over the past decade. Printed paper has given way to eBook readers, and the format has also changed from doc to ePUB.
eBook readers require the documents or books to be in ePUB format. The format provides more control to the readers and preserves the usability of the content. Writers need to keep up with this change and provide their books or documents in the ePUB format in addition to the standard doc format.
You may wonder why it is the responsibility of the writer to do so and not the publisher and how to perform this conversion.
