It would be really useful to have the following additional way of filling incomplete metadata, in addition to manual edit and auto-update.
It’d be called something like “update with Online Search”. It would let you issue an online search, reusing the already existing functionality of online search for new articles available under “Add papers”.
You can then select a result from the search and associate it to your existing incomplete record – essentially saying “it’s this one, associate the metadata to my record”.
I think it would be especially useful for those cases resulting from the upload of a PDF you already have in which auto-update fails and little to no metadata are filled automatically. It’d be even more useful on a bulk upload in which metadata cannot be retrieved in a few cases.
What do you think?
