For Galway, there's Foirisiúin Focla as Gaillimh, though it's out of print (unless RIA has decicded to reprint it) and difficult to find unfortunately. It's not just Conamara and Cois Fharraige, but also gives a lot of words from the Eachréidh. Every word in there is either not found in Ó Dónaill or has a meaning not listed by him, so it's handy to have. It is entirely in Irish though.

There's also Liosta Focal as Idir Shúgradh is Dáiríre in the same series. This is a word list from one of Ó Cadhain's books, words and phrases which aren't found in Ó Dónaill. Shame their lists for the rest of his works were never published.

Galaxyrocker, maybe you can find the dictionaries in a library and transcribe them on a website? Let us know what site you're doing that on.

Thank you, Galaxyrocker!
