Scholarship never ends. There is never a last word, even about established facts. What we've had up till now in published works are static snapshots. Sure, there may be follow-up articles, second editions and corrections, but each work stands alone as a completed product. I find myself wondering if researchers - and writers - will continue to be content with snapshots when the technical barriers to revision are so low and readers' comfort level with edited online works is growing.
Ergo, we need other ways of publishing - online, wikis etc. Not rocket science, but definitely something of a leap for the academic world. (Via Open Access News.)
