Bird checklist historical comparisons

You can use this page to compare any 2 historical versions of a published checklist. For example, you can use this tool to see what changes have occurred between the 6th and the 7th edition of the AOU checklist, or between the 48th and the 49th supplement. New (Jan 2013): Cross-checklists comparisons are now available! For example you can now compare any version of Clements and the IOC checklists (cross-checklists comparisons are only available for global checklists). You can now also restrict the list of changes to a geographic region (e.g. a country, a province or a site) to see only changes affecting birds in a specific area.
