I know from previous posts on here that there are some big problems with accessing LDS Family History Centres in Ireland, so hopefully this might help.
Earlier this year Familysearch announced that they were opening up their photoduplication service to email requests.
So if you send them detailed information about a particular record you want, and they have the microfilm, then they will email you a high quality scan of the page with the relevant record.
You have to send very specific info: You MUST include the Film or Fiche number, item number, Name of Individual you are researching, Title of record and name of parents, spouse, grantor, grantee, etc, Event type (Birth, Death or Marriage), Complete event date and place, Parish and volume or page number and registration or Certificate Number, and state or country of origin and any other information that will be helpful in locating your record.
I tried with one request to see if they would do it even though I have a couple of Family History Centres near me.
I emailed them with a request on 6 Feb and got a brilliant scan of a Co. Laois parish register page yesterday, via email.
So even if you can't make it to the NLI/National Archives etc.. either and have the exact date of a record then you can get a scan via email as long as the LDS Family History Library has the microfilm.
