Dictionaries and dictionaries generally consist of text, auxiliary descriptions, directories, indexes and related appendices. Encyclopedia is based on items. Entries generally consist of titles, explanations and references. There are generally three ways to arrange items: according to the first word order, classified arrangement, and combination of classification and word order.
In order to facilitate retrieval and expand the scope of use, modern encyclopedias also have contents closely related to the text: preface, examples and tables of contents, illustrations, indexes, informative and informative appendices (such as memorabilia and atlases).
Features of reference books:
1. For editing purposes, it is mainly used for reference and retrieval, not for reading through.
2. As far as the arrangement is concerned, reference books are always arranged in a certain style to reflect their reference books and facilitate reference.
3. As far as the content is concerned, the existing research results are widely absorbed, the knowledge and information provided are mature and reliable, and the narrative is concise and to the point.
