A history book is a text that compiles verified and authoritative information about events relevant to a country or region. Depending on the type of approach, it may include the author's interpretations or additional annotations. It should always be made explicit whether the text is objective or subjective.
History books are often very diverse and cover different aspects or important episodes. They also offer different perspectives on the same topic, allowing the reader to enrich his or her knowledge and make his or her own value judgements.
The disadvantage, in contrast, lies in the difficulty of providing homogeneity in the delivery of information. History, as we know, can be told in many different ways. Therefore, it is common for there to be variations in discourse depending on the publisher and its commercial or ideological interests.
