The following policy was approved through voting by e-mail, effective from Dec 4, 2007:
The IW3C2 will routinely grant permission for copying paragraphs and figures in its proceedings without charge, as long as proper citations are given. It will facilitate communications with authors to obtain figures in better quality, or to obtain original data to plot the figures.
In the case of reprinting an entire article for distribution or for inclusion in other printed publications with proper citation, the IW3C2 will impose a charge of US$500 if the re-publication is for commercial purposes, or US$100 if it is not.
