Tracking changes is important when content becomes fluid, as it does in digital forms. There have been, for quite some time, Web page watchers that send an e-mail message when a page is updated. WatchThatPage is one example. I use this to keep track on some important Web pages such as the MARC Announcements. Other sites providing the same service are ChangeNotes and WebMon.

Blogs and Wikis use an automated Ping system to inform Web services that changes have been made. WikiPing and Weblogs.Com are the two examples of those systems. There are many more for 'blogs but a simple Web form is available to easily ping all available services.

CVS has been a standard for tracking changes in software. Now there is Subversion, the new publication Version Control with Subversion alerted me to this new tool.

These tools can alert us to changes on a page, but how often should we check to see if they are great enough to change our bibliographic record? With content being so fluid, does it matter, should we leave it to the Web services, or find some means of updating our records via ping? Or do we only consider more document-like resources? Just some random thoughts.
