Technically you can fix some of the errors in cataloguing by creating an account at openlibrary.org which is where this data comes from BUT for Irish language authors (& probably a lot else) this is a huge rat’s nest of mistakes and duplicate entries. I have spent days trying to sort out some of this, but at the end of the day there are limits to what an ordinary user is allowed to do, so you have to meticulously compile a list of URLs in a text editor and then e-mail a librarian, who may or may not have time to actually do it. I understand that they don’t want their data being corrupted by just anyone, but this process is so tedious.

Seo scéal Thomáis Uí Chromhthainn faoi láthair m.sh.
“Tomás Ó Crohan” — íomhá + dátaí iomlán, 20 saothar luaite
“Tomás Ó Criomhthain” — bliain (breithe/báis), 2 saothar luaite
“Tom Criomhthain” — blianta, 0 saothar!
“Tomas Ó Criomhthain” — blianta, saothar amháin

Concur with first review. Would be good if this could be corrected.
National Library of Ireland record is here:
https://catalogue.nli.ie/Record/vtls000308523
Title is : An t-Oileánach
Author's name: Tomás Ó Criomhthain
There are separate records in archive.org for the same author under the English version of his name Tomás Ó Crohan. Would be good to link these. It's the same person after all!

And the author's name is Tomás Ó Criomhthain.

If these could be corrected, it would be a lot easier to find this book here!
