John Cowan writes in a new comment to this 2010 thread:
The Internet works in mysterious ways its wonders to perform, and some news is good news.
After They Who Shall Not Be Named reneged on their promise to make GDoS searchable with a “We won’t do it: sue us if you dare”, Green was left with the digital database rights but nothing to do with them. Academia and industry alike turned him down with “What’s in it for me?” He tried hiring programmers, but the ask (“megabucks”) was beyond his means. Finally, David Kendall offered to do the work gratis, just because it needed to be done (dpk is a student of historical linguistics as well as a programmer) and today https://greensdictofslang.com is online. Headword search, definitions, and etymologies are free; advanced search and supporting quotations are available to individuals by subscription at £49/year (currently about US$60). Institutional subscriptions are also possible: rates on request.
I have a subscription (it would be a solecism to assert that this has any connection with my occasional IRC conversations with dpk over the years) and will be pleased to look up anything that other Hattics can’t get for themselves.
This Is Good, as they say. Thanks, JC (and of course JG)!
