I'm looking to download some papers from a reference list in an Excel file which consisted of all the basic info about a paper (e.g., author, year, title, publication, etc.) but unfortunately not the DOI. I've looked into many methods for batch downloading papers, but they all require the DOI to work. I've also looked into searching for DOI using the title of the paper but to no avail, as all the programs I've came across does the reverse, i.e., use the DOI to retrieve the rest of the metadata. I would greatly appreciate any pointers anybody has.
You can submit batches of references to get DOIs manually through through Crossref Simple Text Query - https://apps.crossref.org/SimpleTextQuery
