What are the differences between ISBN and DOI and how do they impact the identification and retrieval of academic publications?

ISBN (International Standard Book Number) is used to identify books and monographs, while DOI (Digital Object Identifier) is used for academic articles and other digital documents. ISBN is specific to books, while DOI is more versatile and can be used for various types of digital content. DOI is more commonly used in academic publishing because it provides a persistent link to the content, making it easier to retrieve and cite academic publications.
