Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

See this entry: https://directory.doabooks.org/handle/20.500.12854/35818

Search for “Accounts and Accountability in Late Medieval Europe” in JabRef DOAB websearch.

It finds:

University of Bucharest in the frame of the European Research Council
project CASTELLANY ACCOUNTS, “Record-keeping, fiscal reform, and
the rise of institutional accountability in late-medieval Savoy: A source-oriented
approach”. Both the conference and the volume have received funding
from the European Research Council (ERC) under the European Union’s Horizon
2020 research and innovation programme (grant agreement No. 638436).
The volume traces the momentous transformation of institutions and administration under the impact of accounting records and procedures, c. 1250-1500. The focus on the materiality and organising logic of a range of accounts is complemented by close attention to the socio-political contexts in which they functioned and the agency of central and local officials.},

Hi @shafinkamal yes, you are welcome. If you look at how the other fields (e.g. title, date, pages etcetera) are implemented and fetched, you might be able to add the ISBN field similarly. If you read carefully, I think most, if not all relevant information to solve this issue has already been presented in previous comments. A first step would be to look at the code of the previous pull-request that implemented the DOAB fetcher.

@ThiloteE Hi, there are two questions here, I think:

1. Where can I find the ISBNs? In short, the ISBN is part of the metadata connected to the BITSTREAM. There might also be additional ISBNs in oapen.relation.isbn; dc.identifier.isbn
2. How can I access a filed like"oapen.imprint"? These fields - when they are part of the record - can be accessed via the API

Perhaps you can take a look here: https://directory.doabooks.org/rest/search?query=handle:"20.500.12854/26303"&expand=metadata,bitstreams

Both issues are addressed. Hope this helps!
