Hi Isaac, The following DOIs are failing because the ISBNs have already been assigned: | DOI | Frontend | CR sub ID | | --- | --- | --- | | [https://doi.org/10.51952/9781447369318](https://doi.org/10.51952/9781447369318) | [Critical Social Work with Children and Families – Theory, Context and Practice | Bristol University Press](https://bristoluniversitypressdigital.com/display/book/9781447369318/9781447369318.xml) | 1614681170 | | [https://doi.org/10.51952/9781847429438](https://doi.org/10.51952/9781847429438) | [Evidence, policy and practice – Critical perspectives in health and social care | Bristol University Press](https://bristoluniversitypressdigital.com/display/book/9781847429438/9781847429438.xml) | 1656974747 | | [Lesbian, Gay, Bisexual and Trans Health Inequalities](https://doi.org/10.51952/9781447313519) | [https://bristoluniversitypressdigital.com/edcollbook/book/9781447313519/9781447313519.xml](https://bristoluniversitypressdigital.com/edcollbook/book/9781447313519/9781447313519.xml) | 1656974639 | | [https://doi.org/10.51952/9781447360667](https://doi.org/10.51952/9781447360667) | [Community Development, Social Action and Social Planning – A Practical Guide | Bristol University Press](https://bristoluniversitypressdigital.com/display/book/9781447360667/9781447360667.xml) | 1656974637 | | [https://doi.org/10.51952/9781529242249](https://doi.org/10.51952/9781529242249) | [Exiting the Factory (Volume 2) – Strikes and Class Formation beyond the Industrial Sector | Bristol University Press](https://bristoluniversitypressdigital.com/monobook/book/9781529242249/9781529242249.xml?rskey=GaZgZH&result=1) | 1656974748 | I believe the last time that this happened it was because of minor inconsistencies in Bristol University Press’ metadata, when compared to some of our distributors. Please can you overwrite so that the following DOIs are functional? Let me know if there is any other information that you need or if I’ve misremembered the process for doing this. ---

Hi Enzo, Thanks for your message. All of these deposits failed because of a title discrepancy between the ISBN title names registered in our system versus the one you had indicated in the submissions. I have updated the record title names we had in our system to match the ones you had in your deposit, and then rerun these submissions. These content is now registered. Best, Evans ---
