MEZA CASTRO, Marvin David. The source of visual information and visual communication: Image. Notes on information and library science. E-Ciencias de la Información [online]. 2018, vol.8, n.2, pp.102-121. ISSN 1659-4142.  http://dx.doi.org/10.15517/eci.v8i2.29956.

This essay provides a definition about image as a source of information and communication, based on the idea that images (mainly digital images) have become essential in the process of communication and information transmission in globalized societies. Consequently, the image builds a visual culture developed from the signs and elements transmitted by a visual language. This essay is aimed at identifying relationships between the images, as source of information and communication, with library and information science. Moreover, it emphasizes methods and techniques of information retrieval and content-based analysis, and suggestions for the process of human and automatic indexing of visual information sources. Both, Content Based Image Retrieval (CBIR) technology, as well the importance of Visual Literacy for the information and library science are addressed. The essay concludes that the role of the image today, as an element of communication and transmission of information, must be reconsidered and confronted by the information and library science.
