"Two years after the publication of the 2nd Edition of The International Headache Classification (ICHD-2), we are now ready to launch a web based edition. This web based version has many facilities that are not present in the printed version or a simple electronic file.
Since a Headache Classification cannot be learned by heart, it is of immense value that doctors all over the world are now able to go on the web and look after whatever question they may have regarding ICHD-2."
