This script runs on search results, item details, and digitised file view pages in the National Archives of Australia's database RecordSearch.

It does three things:

• If a file is digitised, it retrieves the number of pages in the file and displays it as part of the link to the digitised file. This means you know without clicking through whether the file contains 1 or 300 pages.
• It also rewrites the link to the digitised file to STOP IT OPENING IN A NEW WINDOW. The default behaviour is just so annoying.
• On a digitised file view page, the barcode is turned into a link back to the item details page.

To install this in Chrome, first add the TamperMonkey extension. Then just click on the 'Raw' button above. Tampermonkey will then ask you if you really want to install it. Click install!

For Firefox, you'll need to install either the Tampermonkey or Greasemonkey plugins. Then just click on the 'Raw' button above. Your userscript manager will then ask you if you really want to install it. Click install!
