Seems like possibly the data is out of sync between polite and non-polite pools? I don’t know if that’s possible with your backend setup, but a user report from using `habanero` suggest it is possible

See [Library returns wrong values · Issue #159 · sckott/habanero · GitHub](https://github.com/sckott/habanero/issues/159#issuecomment-1927874811) for the discussion - just reproducing the salient part here:

without polite pool

```auto
 curl https://api.crossref.org/journals/2448-1904 | jq .message.subjects

[
  {
    "ASJC": 2505,
    "name": "Materials Chemistry"
  },
  {
    "ASJC": 2002,
    "name": "Economics and Econometrics"
  },
  {
    "ASJC": 2214,
    "name": "Media Technology"
  },
  {
    "ASJC": 1107,
    "name": "Forestry"
  }
]

```

with polite pool

```auto
curl -H 'User-Agent: (mailto:myemail@gmail.com)' https://api.crossref.org/journals/2448-1904 | jq .message.subjects

[
  {
    "ASJC": 2700,
    "name": "General Medicine"
  }
]

```

Hi @sckott . Thanks for flagging this to us.

We’re aware of the two pools getting out of sync. Our technical team has been working on a fix for several weeks. We have a few Jira tickets in about it, so you can see the different flavors of problems: [[CR-1531] - Jira](https://crossref.atlassian.net/browse/CR-1531) , [[CR-715] - Jira](https://crossref.atlassian.net/browse/CR-715) , and [[CR-1558] - Jira](https://crossref.atlassian.net/browse/CR-1558).

You can follow any of those individual tickets, if you are interested. We’ll also be updating our status page with the latest: [Crossref Status - Small portion of metadata records not being indexed by REST API](https://status.crossref.org/incidents/zftk4pmztjh8)

Thanks again,  
Isaac

Hi @sckott ,

I wanted to follow up on your message to us from February to let you know that we have removed the ASJC subject codes from our REST API. We’re no longer asserting subject areas/codes for journals/journal articles.

Warm regards,  
Isaac
