@Magnus Manske, Charles Matthews, Jakec: I think we have a glitch here - just realised that as originally suggested isn't an appropriate link; this only works if a free version of the article is up (and these tend to be temporary, rotating weekly). The actual articles are located at if we're using the "short" ODNB numbers as at Q430712 or (note trailing slash) if we're using the long 101-prefixed OBIN numbers as at Q1063507. Andrew Gray (talk) 21:33, 15 July 2014 (UTC) fact, unless my browser is going weird, they all seem to link to the sample page (which is also now broken). Andrew Gray (talk) 21:39, 15 July 2014 (UTC)
@Andrew Gray: That was a mistake in the AuthorityControl script. I've fixed it. --Jakob (talk) 21:52, 15 July 2014 (UTC)
@Jakec: It now goes to - this gives an error :-). Could we switch it to instead? It looks like almost all uses use the 101- form so we should probably standardise on this. Thanks! Andrew Gray (talk) 22:08, 15 July 2014 (UTC)
Relatedly, I've just discovered that P1384 (P1384) is an OBIN property. We probably don't need both, and that's only used on three pages; should we deprecate one? Andrew Gray (talk) 22:01, 15 July 2014 (UTC)
@Jakec: I have written a tiny script that will redirect to the appropriate URL, depending on the presence of the 101 prefix: That should take care of the immediate issue.
@Andrew Gray: I just checked all ~550 items with Oxford Dictionary of National Biography ID (P1415); turns out only Charles William Miller (Q430712) has the "short" version, all the others have the 101 prefix. There are only 2 (two) items with P1384 (P1384) at the moment. --Magnus Manske (talk) 08:11, 16 July 2014 (UTC)
@Magnus Manske: Great - in which case I'll mark the other one as deprecated and relabel this one as OBIN (with appropriate alternate names) since we're standardising on the 101- form. Andrew Gray (talk) 18:56, 16 July 2014 (UTC)

Known errorsEdit

  1. "David Saunders" is George Saunders = George Saunders (Q18810744). --Kolja21 (talk) 21:34, 8 August 2015 (UTC)
This isn't actually an error. The ODNB has a few thousand "secondary" entries, where a second person is dealt with inside another article - usually a more important relative but sometimes a thematic group of people. A number gets assigned for each person, and both resolve to the same article (with an anchor in the text at the first time each name apears). In this case, the main article is George (40964), and it also covers his father David (40967). Andrew Gray (talk)

Short IDsEdit

@Charles Matthews, Andrew Gray: I tried to add P1415 = 190 for Ælric (Q8077305) to link to but the link doesn't work.

Having read through the above comments, is there something special that needs to be done for "short IDs" like this? Jheald (talk) 13:42, 1 February 2016 (UTC)

  Done Got him. Turned out I could look him up at which gave me the long-form version of the ID, in this case 101000190. Jheald (talk) 13:52, 1 February 2016 (UTC)
And also remembered to find and redirect Ælric (Q18526324), since if there is a new ODNB link to make, that means there must also be a wikidata item created to have that link that needs to be merged. Jheald (talk) 14:20, 1 February 2016 (UTC)
Good catch. The constraint report will hopefully pick the duplicates up should you miss them, though. Andrew Gray (talk) 12:34, 2 February 2016 (UTC)

OK, the point is that the OBINs are all padded out to have nine digits. And you do that by adding enough initial digits from 101000000. The "normal case" is therefore that you put 1010 in front of a five-digit number; but there can be six digits, as well as fewer. Charles Matthews (talk) 15:45, 1 February 2016 (UTC)

New URLsEdit

@Andrew Gray: The ODNB has just had a new skin (Oxford Blue (Q7115244), natch), and probably numerous editorial changes to the supporting text. It also has new URLs, and at first sight anyway simply changing the formatter URLs won't do.

A typical URL is now like, formed with the shorter form rather than the padded 101064900 OBIN. If that is a DOI, it is then supposed to work permanently. But right now there are broken links. Charles Matthews (talk) 16:04, 27 November 2017 (UTC)

Oh dear. Hmmm. This is going to be a bit of a challenge to deal with. I think our options are:

The first of these seems like the best solution to me - it's easy for reusers to understand and means we can keep the 1:1 connection between this property and the ODNB. I'd always wondered how we were going to handle non-ODNB material through this, given that we use "has P1415" as a proxy for "is in the ODNB". Unfortunately, it will be a complex task - we'll need to re-import all the IDs in the new form. This is straightforward enough but will mean ~150k bot edits. Shall I start working out how to do it? Andrew Gray (talk) 12:40, 28 November 2017 (UTC)

Preparting this just now; see related discussion at Wikidata:Project chat#Oxford Biography Index Number (P1415). Andrew Gray (talk) 20:24, 2 December 2017 (UTC)
About 45k of the 120k total edits now done; may take until Monday morning to get everything sorted. But grinding away at it... Andrew Gray (talk) 10:39, 3 December 2017 (UTC)

About to run this. Things to check after the migration -

  •  Y All old forms removed
  •  Y All new forms added
  •  Y Check against old list to make sure none got lost
  •  Y New formatter URL
  •  Y Usage notes updated
  • Authority control script (not needed now)
  •  Y Formatter URLs corrected on wikis using this data (ar, cy, any others?)
Will check through these shortly but looks like we're good. One major problem, though - it makes it difficult to find the number for a "secondary" article. See eg 16978 (which is merged in with 16977); the only way to identify this DOI is to go right down to the bottom and use the "see also" link. This displays in the same way whether the "see also" is the secondary person in the main article, or a linked relative with a different article. Not great - we'll have to keep a close watch on duplicate IDs. Andrew Gray (talk) 11:23, 23 December 2017 (UTC)

More URL woes?Edit

@Charles Matthews, Andrew Gray: Recent ODNB additions such as Noble, Mary Eleanor - - Mary Eleanor Noble (Q66311425) - have DOIs in the form and DOIs produced by our formatter produce 404s - e.g. see this oldid producing (139498 may not event be her ODNB ID. Who knows. --Tagishsimon (talk) 22:53, 11 August 2019 (UTC)

I'm getting the same thing with for Peggy Crewe-Milnes, Marchioness of Crewe (Q75285257). I've recorded the link as described at URL (P973) instead of Oxford Dictionary of National Biography ID (P1415). From Hill To Shore (talk) 22:13, 12 June 2020 (UTC)
