A virtual book is a digital version or electronic representation of an actual physical book. It can be accessed and read on various devices such as computers, tablets, e-readers, smartphones, etc., using specialized software or applications designed for reading digital content. The text, images, and other elements are presented in a way that simulates the experience of holding and flipping through an actual book. Virtual books can be purchased or downloaded from online stores, libraries, or directly from publishers, and they often offer features such as adjustable font sizes, highlighting, note-taking, and searching capabilities.
