Updating Local Books Online by Using a Download File

Each local copy of SQL Server Books Online lists the month and year it was built in two locations:

  • Each SQL Server Books Online topic lists the update version immediately above the topic title.

  • The update version is listed in the title bar of the DExplore help viewer if you open the SQL Server 2008 R2 Books Online from either the SQL Server 2008 R2 program group or from SQL Server Management Studio.

The SQL Server 2008 R2 Books Online download Web page lists the date the update was built at the top of the page. If the date listed on the download Web page is newer than the date of your local copy of SQL Server 2008 R2 Books Online, you should update your local copy by installing the update from the Web site.

Updateable Copies of Books Online

Multiple Copies of Books Online
