Page history

A page history shows the order in which changes were made to a ISOGG Wiki article or other page on the ISOGG Wiki. Every editable page on the ISOGG Wiki has an associated page history (sometimes called revision history or edit history), which is accessed by clicking the "View history" tab at the top of the page.

The page history contains a list of the page's previous revisions, including the date and time (in UTC) of each edit, the username of the user who made it, and their edit summary.

Using a history page

Overview

On a history page:

• All past changes to the page in question are listed in reverse-chronological order.
• To view a specific version, click a date.
• To compare an old version with the current version, click cur.
• To compare a version with its predecessor, click prev.
• To compare two specific versions, tick the left-column radio button of the older version and the right-column radio button of the newer version, and then click the "Compare selected versions" button.
• Minor edits are denoted as m.

Below is a short example of a page history using the default skin:

Edits are shown from newest to oldest. Each edit takes up one line which shows the following as tagged by numbers in the screenshot above.

1. Compare selected revisions button when clicked will take you to a page showing the difference between the revisions to a page. Use the 'radio buttons' to select revisions to compare.
2. (cur) takes you to a diff page, showing the difference between that edit and the current version. The current revision appears below the changes, so you can see how the page is now rendered.
3. (prev) takes you to a diff page showing the changes between that edit and the previous version. The most recent version (the one on the same line as the "last" you clicked on) appears below the changes, so you can see how the page was rendered.
4. Time and date of edit This gives the time and date of the edit, expressed in local time according to the preference setting. The date and time 'link' to the version of the page at that day and time. Thus the first line links to the version that was current at the time of loading this revision history, and therefore the result may differ from that of following the link on the page margin to the current version.
5. Size of the page in bytes (roughly corresponding to characters), additions or deletions. The difference in size between this revision and the previous revision.
6. Username of the contributor which will hyperlink to their user page.
7. m stands for minor edit or lacking an m means the contributor to the page felt the changes were not minor.
8. Edit summary is the text the user wrote in the edit summary box (below the edit box). If edit summary begins with an arrow link and grey text. This means the user has only edited a section of the page (named in the grey text). This text is automatically added when you edit a section. A standard edit summary can be added by the user. This appears in black text.
