With the The History Browser you can browse through the history of an object. The History Browser provides three main areas:
 * '''List of object versions''': on the left a list of object versions is displayed. Two versions (A and B) are marked with a dot.
 * '''Values of version A''': this panel displays the values of version A 
 * '''Values of version B''': this pnale displays the values of version B

You can manually place both dots or click on a date or user name to place two dots at once. You can also use the up and down arrows on your keyboard to move the dots up and down. 

=== Basic information about a version ===

The History Browser displays basic information about each object version:

  * the '''version id''', a unique number the OSM server assigned to this object version
  * the '''date of creation'''
  * the '''user''' who created this version. Click on the link to launch a browser with additional information about the user.
  * the '''changeset id''', i.e. the unique number of the changeset in which this object version was created. Click on the link to launch a browser with additional information about the changeset.
  * the '''changeset comment''' (if availible)
  * the '''changeset source tag''' (if availible)

Via a right click on a version in the list of object versions, you can:

 * [[Image(source:josm/trunk/images/data/user.png,16,middle)]] Lauch browser with information about the user

=== Object dependency ===
Depending on the [wiki:Help/Concepts/Object object type] which is selected, there is a different second tab on the right part of the window.

==== Node ====
The '''Coordinates tab''' displays the longitude and the latitude of the node and the distance if the position of the two selected versions is different.

==== Way ====
The '''Nodes tab''' displays all nodes of the way with their id.

==== Relation ====
The '''Members tab''' displays all members of the relation with their id, an icon of their object type and (if set) their role.
