External persons, usually associated with contracts, are known to GLPI as `Contacts`. A contact is characterized by usual identity information as well as title, phone number, mail address... Defining a list of contact types allows to sort contacts by types. It is also possible to export a contact in vCard format. ![A contact in GLPI](https://2965217165-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FBk8u0TPogHtiUd7DaQyf%2Fuploads%2Fgit-blob-5572d3f5a38efe45c0d03f45a1a08eb2ff7b110b%2Fcontact-en.png?alt=media) {% hint style="info" %} The list of possible titles for a contact is the same as the list of possible titles for users. {% endhint %} *** ## Suppliers The *Suppliers* tab is used to show or add linked suppliers. Go to Suppliers *** ## Documents The document tab lets you link different types of file to a material (PDF, txt, png, etc.) You can attach a document already uploaded to GLPI or add a new one directly from this tab. Go to Documents *** ## Links Links offer several possibilities. Send the GLPI object file to another URL of your choice, or generate an RDP file, for example. Go to Links *** ## Notes Note lets you add enriched text and attach a document. Go to Notes *** ## History The *History* tab is used to show any changes made to an item. The following information about the changes is available: * ID of the change. * Date and time the change was made. * User who made the change. If this field is not filled, it means that the action was done automatically (For example: automatic inventory update). * Field that was changed. * Description of the change that was made. The description of the change represents either the difference between the old and the new value (For example with location field: Change HQ to Remote Office A), or the explanation of the action which was carried out (For example: Uninstallation of a software: "Gimp 2.0"). {% hint style="info" %} For dropdowns or objects with a parent/child relationship, the modification of a child will appear in the history of the parent element. {% endhint %} *** ## All Information For an item, all information is displayed on one page from the *All* tab. This shows all of the tabs of an object's form in one view, one below the other.
