The concept cross-reference refers to all information that appears in a text and is equivalent to another document . It is, therefore, a signaling system that allows the reader to find specific and broader information.
Cross-references are used in conventional printed documents (novels, essays, textbooks or research papers) and on the internet . Anyway, there are several types of cross-references, among them: the asterisk, a small number that accompanies a word in a text (such as footnotes), an explanatory table, a hyperlink, bullets, images, listings of numbers, etc. In this way, just as the reading of a printed document is used as a marker to indicate a word or paragraph , in the virtual reading there are indications that allow the identification of information.

Finally, we can understand cross-references as a tool or tool at the service of knowledge.
In Word, Excel and other programs
When working with Word cross-references become very useful. Through them we can have a marker or any image. To facilitate its operation, Word programs have incorporated the option of cross-reference.
Through this option we can choose, select and insert the element we want to reference (for example, a marker). Thus, some examples of cross-references in Word are as follows: back to page 4, observation of table 3, illustration 6, among others.
Programs like Acces or Java also use cross-references as working tools.
