Category talk:Articles with invalid ISSNs

Limit to mainspace articles
Maybe this template should be changed to only list mainspace articles? i.e. at the moment, we should have 0, not 1, in our list. Keesiewonder talk 18:46, 11 February 2007 (UTC)

How to fix page
or any : Hors d'oeuvre is listed as a page with invalid ISSNs. How to find out which ISSN easily? Cheers! 22:04, 15 January 2016 (UTC)
 * Checkingfax, looks like you figured it out. I updated Template:Please check ISSN so that it will show a visible error in preview mode. this message is not shown after the article has been saved, only when viewed in preview mode. Frietjes (talk) 15:06, 16 January 2016 (UTC)
 * Also see this discussion. It looks like ISSNs without hyphens are causing this error, which may not be what we want. – Jonesey95 (talk) 15:09, 16 January 2016 (UTC)


 * Hi, I was being lazy because I thought I was going to have to review 100 ISSNs but after posting here when I searched the page there were only two total ISSNs, and only one ended up being invalid. But then when I found the right Worldcat page I took the ISSN number from the URL—‌but that was only 7-digits and did not work. So then I thought it might be the template so I switched to issn=, and that did not work; so I thought about putting a dash it it; I tried the old ISSN but it did not work even with a dash, so then I finally scrolled down the Worldcat page and found the correct ISSN was listed in a line below-the-fold. Once I plugged in the correct ISSN it worked. Now I shall switch back to the template, to honor the way it was. Thank you for your efforts. I like those soft warnings in the edit notice tha there are errors in template paratmeters, or that an incorrect parameter has been invoked in a template. Those errors are a puzzle to solve for me sometimes. They are rarely of my doing. Sometimes the hard part is to figure out what new parameter to replace the invalid parameter with and then which parameter data do move where to preserve it. Sometimes in reference parameter errors it will say something like "chapters parameter unknown"—‌"try chapter". With issn= does it have to use dash or no dash? I read about the  template and it said it could go either way. Could the edit preview chide mention that ISSNs are always 8-digits? Cheers!   03:30, 17 January 2016 (UTC)

Backlog
et. al. The page has now a backlog. Can someone please help? -- Magioladitis (talk) 20:23, 27 January 2016 (UTC)

can you please check that the chechsum in case the last digit is X works fine? I see that ISSN 1416-300X yields an error while I see this here as a valid ISSN number. -- Magioladitis (talk) 20:45, 27 January 2016 (UTC)
 * Magioladitis, according to WorldCat its, but could be or ? Frietjes (talk) 21:43, 27 January 2016 (UTC)
 * no idea. I wonder why the wrong ISSN does not show a warning in the page the same way all ISBN errors do. It's very difficult to spot the error when there are multiple ISSN numbers sometimes. -- Magioladitis (talk) 23:12, 27 January 2016 (UTC)
 * I find that the error message shows only when I go into Edit/Preview mode. I haven't tried to figure out why that is.


 * I will look through this backlog to see if I can find any patterns. I previously cleared out Category:CS1 errors: ISSN, which had a few thousand (IIRC) articles in it. On the way, I developed an AutoEd script that helped fix about 75% of them. Also pinging, who might be interested in this category.


 * P.S. ISSN 1416-300X is invalid. Here's a validator. Journals very occasionally print invalid ISSNs in their issues and on their web sites. Humans make mistakes, just as WP gnomes do. If I get desperate and can't find a valid ISSN, I usually swap it with a valid OCLC number and template. – Jonesey95 (talk) 23:28, 27 January 2016 (UTC)


 * The ISSN template calls Please check ISSN when the ISSN fails validation. The latter template's documentation contains the following explanation: "In preview mode, it shows the warning message . This warning is shown only in preview mode." – Jonesey95 (talk) 04:10, 28 January 2016 (UTC)

I just fixed about 20 of these, and so far, there is no discernible pattern. Most of the errors have been typos, fixable with WorldCat searches with a small fraction being just missing hyphens between the two groups of four digits. – Jonesey95 (talk) 04:37, 28 January 2016 (UTC)
