Whilst I agree with Claire Santry's review in March that the new design is much fresher (although I'm not a fan of the boxes flying up from the bottom of the screen ...), I've had a really good roam around the site and do think that there is a lot of repetition and some curiously clumsy advice given for accessing post-1922 wills (see my page highlighted above for my own opinions and alternative options.)
However, whinging aside, there is lots of good advice and of course a veritable smorgasbord of FREE Irish records to be had on this official site - fill your boots, as they say!
One link I could not see how to restore via the NAI was that to Herbert Wood's 1919 guide to the records. However, Sean Murphy has recently published a facsimile version of this guide with an excellent essay as a preface, so I've included that link on my NAI page or you can access it directly via the link above.
Sean has been busy as he has also updated his excellent free Primer on Irish Genealogy, which is well worth a read. I also recommend taking the time to explore the rest of his Centre for Irish Genealogical and Historical Studies website where he has freely shared other essays and advice. In fact, I've just spotted his Guide to the National Archives of Ireland and am settling down for a good read now!
