Yearbooks
Yearbooks are also called as annuals. As it is evident from the literal meaning of the term, a yearbook is a serial publication issued every year. It is called a compendium because it provides comprehensive account in a concise form of otherwise a vast subject. It contains current information on one or more subjects - in brief, descriptive or statistical format. Yearbooks are published like as independent publications or as supplements to an encyclopaedia. Thus, year-books can be categorized into two major groups:
a) Yearbooks
b) Supplement to Encyclopaedias.
