The article discusses the techniques used in locating a specific type of image or file in the U.S. Because of the existence of different types of images which varies in color, type and description, it is difficult for user to locate a specific image that he wants. Previously, the Library of Congress uses Thesaurus for Graphic Materials I and Thesaurus for Graphic Materials II in cataloguing and retrieving images. With the onset of new technology, collaborative tagging is used in assigning keywords to textual documents and image resources. Such a tool is used by sharing sites such as Flick because it allows massive image storage and web diffusion wherein users upload their own images and index them using their own tags.

This article focuses on literature related to the United States-Mexican border region. The United States-Mexicans border is a point where two diverse cultures meet and intermingle. Historians, public servants, legislators and others who are intimately concerned with the situation have long recognized the region as a somewhat unique area; the concept of uniqueness has been expressed in various ways, depending upon the orientation of the individual concerned. The author of the article informs that the purpose of the guide is to aid researchers dealing with contemporary situations. Within this concept one might legitimately include all historical works dealing with the area, since history is a continuum and conditions of the sixteenth century have had their influence on the institutions of today. But it would be manifestly impossible to include all historical writing on the area, and as a consequence an arbitrary line of distinction has been set; with few exceptions, and then only if the work is particularly applicable, the guide includes material dealing only with the period after Mexican independence.
