I use zotero for managing all the papers of my collection. For new ones and those published in "referenced" reviews this works very well, however I have a lot of very old papers or papers that are published in small journals without DOI. When I look for them in google scholar, I find them immediatly and correctly referenced and I can export a citation. I was wondering if there was a possibility to create a parent item for a pdf I add in the collection using a citation like the one below, instead of the time-consuming process of adding manually author, date, journal, etc.
In the settings of zotero, I have google scholar as one of the engines used for searching metadata, but apparently it is not working.
An example of citation that contains everything you need for creating a parent item:
"WALLACE, Alfred Russell. On the physical geography of the Malay Archipelago. The Journal of the Royal Geographical Society of London, 1863, vol. 33, p. 217-234."

Thank you in advance
