Reconciliation returns wrong item - titles match but DOIs don't

[Dominic-DallOsto]

Describe the bug
I imported this item into Zotero, then tried to find its QID. This item was incorrectly returned. The titles match, but the DOIs are different - apparently the paper with an existing QID is an earlier project description paper.

Is this expected behaviour because a preprint might have a different DOI to a published paper? Or should we always check unique identifiers like DOI before matching titles?

To be honest, from a first glance it wasn't clear to me whether the two items were the same - only after closer inspection.

Environment:

• Zotero version: 5.0.96.3
• Cita version: 0.3.1
• OS name and version: Windows 10

Reconciliation now returns this item as expected

Is this expected behaviour because a preprint might have a different DOI to a published paper? Or should we always check unique identifiers like DOI before matching titles?

As explained here, if a DOI or ISBN were provided, "candidates are first fetched by looking for items with the supplied identifiers". If no candidates are found (or if DOI or ISBN were not provided) the query field (i.e., title) is searched for.

Regarding preprints, in my opinion they should be treated differently from the final publication, as expressed here.

You posted this issue on Oct 22, 2021 around 8:30 am UTC. According to the revision history of the correct item (Q109071931), it was created a few hours later. This would explain why you finally got this QID a few days later.

I wonder whether you got an exact match, though. You should have got a partial match because the titles do not match exactly:

• article: COVID19 Disease Map, a computational knowledge repository of virus–host interaction mechanisms
• preprint: COVID-19 Disease Map, a computational knowledge repository of SARS-CoV-2 virus-host interaction mechanisms

I'm closing this. Feel free to reopen if I misunderstood something.
