The Bible is a compilation of the writings of a number of separate authors - each separate document is known as a "book". It is composed of the Old Testament (39 books), written in Hebrew in the millennium (or more) before Jesus lived, and the New Testament (27 books), written in Greek in the first century CE.
The New Testament contains the information about Jesus, mainly in four "biographies" of Jesus, called "gospels" (from an old word meaning "good news") and named after the traditional authors, Matthew, Mark, Luke and John (the authors' names are not included in the texts).
The Bible has been translated into English (and virtually every other language in the world), and there are many different translations. I suggest you use a modern translation of the Bible, such as the Contemporary English Version or the Todays English Version (or the equivalent in your native tongue), which are available from most book stores or from the Bible Society.
For ease of referencing, all the books have been divided into "chapters" and "verses" which were generally not defined in the original writings. Chapter numbers are shown in large print at the start of each chapter, and verse numbers are shown in small print within the text. In a Bible reference, the book is named first, then the chapter number, then the verse number within each chapter. Thus John 11:35 refers to the 35th verse in the 11th chapter of the book of John.
