When I use the API (https://api.crossref.org/works/10.1109/TBME.2003.812154/transform/application/x-bibtex) for this paper with title "MEG source localization using an MLP with a distributed output representation", I get title={Meg source localization using an mlp with a distributed output representation}.
Note MEG --> Meg and MLP --> mlp.
Please let me know if I should post the issue to some other repo.
