I found this post on Zotero tips on another blog and thought it might be of interest to my researching colleagues:
Some of the tips are probably already familiar to you, but one in particular was completely new to me: Zotero can index your PDFs and make your whole library searchable. (Tip #4)
Have Zotero index your PDFs
Zotero can index your PDF attachments and make them fully searchable, turning your library from a mere linked catalogue into a Google Books of sorts. The option is turned off by default because it relies on an external open source program (pdf2txt) which is not distributed with Zotero. However, Zotero can automatically install it and enable fulltext indexing: simply go to Preferences > Search and click on the ‘Check for installer’ button. For more info see pdf fulltext indexing in the Zotero documentation.
Thank you, Mark at The Ideophone, for that tip.
He also suggests a saved search to keep track of recent additions. I just sort the references by Date Added. But having a “new” group folder for papers that need to be read or have their metadata cleaned up (“ingested”, in his parlance) is a great idea. It’s like a reference to-do list.
Check it out.
