Go to Preferences in Zotero (Edit -> Preferences -> Advanced) and add the library's Volter database's OpenURL web address in the box: https://utuvolter.fi/openurl/358FIN_UTUR/358FIN_UTUR:VU1?
If you then click on the green arrow while the article reference is open and select Library Search, in most cases Volter will take you directly to the full text of the article. (If this does not work, you can always search for the full text in Volter using the name of the journal.)
Adding PDF files to Zotero
Zotero Connector adds PDF files to Zotero automatically. PDF files can also be added to Zotero by dragging the files onto Zotero. Zotero tries to identify the bibliographic information of the article in the PDF. If this does not happen automatically, right-click on the title of the article and select Retrieve metadata for PDF.
The PDF can be added to an existing reference using the toolbar's clipboard icon (Attach stored copy of file) or by right-clicking on the reference.
Reading PDF files and making notes
If a PDF file is stored in the reference, a small PDF logo will appear on the right. The checkmark on the left will display the file:
Double-clicking on a link or PDF file name will open the PDF file inside Zotero. You can add highlights, notes and borders in different colours to the PDF file.
