You can import a bibliography written in Word to Zotero (references typed directly into the document, not using the Word bibliography module).

 AnyStyle.io converts bibliographic references in text mode (Word, etc.) into a format that can be imported into Zotero:

• select the bibliographic references in Word and copy them (Ctrl+C);
• on Anystyle, paste the text into Parse your references here...;
• click Parse x references;
• in section 2. Edit, assign the right information types to the references. To do so, click on the information to be changed and click Assign Label;

For example: in one reference, I notice that “London/New York” is in the Book title line. I select the “London/New York” box, click Assign Label, and then click Location. This step can be tedious and time-consuming.

• in section 3. Save, click BibTeX. An Export.bib file is created;
• in Zotero, go to File > Import and select the Export.bib file;
• check all the references imported into Zotero (authors, item type, etc.).

If your bibliography consists mainly of books with ISBNs, there’s also a magic trick you can use—see Import a list of identifiers.
