In 2009, Torres-Salinas & Moed proposed the use of library catalogs to analyze the impact and dissemination of academic books in different ways. Library Catalog Analysis (LCA) can be defined as the application of bibliometric techniques to a set of online library catalogs in order to describe quantitatively a scientific-scholarly field on the basis of published book titles. The aim of the present chapter is to conduct an in-depth analysis of major scientific contributions since the birth of LCA in order to determine the state of the art of this research topic. Hence, our specific objectives are: 1) to discuss the original purposes of library holdings 2) to present correlations between library holdings and altmetrics indicators and interpret their feasible meanings 3) to analyze the principal sources of information 4) to use WorldCat Identities to identify the principal authors and works in the field of Informetrics.
