The Indexing Initiative is a cross-library project whose mission is to explore indexing methodologies that can assist indexers by providing tools to increase their productivity while maintaining their high quality of indexing.

Please Note: Our apologies - we have had to take down the open access to our tools due to abusive users. Interactive MTI is accessible now with a valid UTS account. We are sorry for any inconvenience this may cause and hope to make our tools openly available again soon.

If you have been extensively using either Interactive MTI -- please contact us and we can provide an easier to use way of processing large sets of data that will not overrun our servers.
