Automated DOI & ArXiv Harvesting for Researchers
Every second spent searching for a DOI is a second lost in research. UtilityBox scans the first pages of your PDFs using regular expressions designed to catch 10.xxxx/xxxx patterns and ArXiv versioning. We provide direct 'Magic Links' that you can use to immediately pull the full metadata into your reference manager with one click.
Extracting ISBNs from eBooks & Digital Monographs
Whether it's an ISBN-10 or ISBN-13, our tool identifies the numerical markers in both the PDF metadata and the visible text. This is essential for librarians and collectors who need to reconcile large digital libraries with bibliographic databases like WorldCat or Open Library.
Professional Research Optimization
Stop clicking through every PDF in your folder. Drop the file, grab the DOI, and move on. It is the ultimate utility for heavy Citation/Obsidian workflows where organizing hundreds of scholarly sources is a daily task.
Frequently Asked Questions
Q: What citation identifiers does the tool find?
A: It scans for DOIs (Digital Object Identifiers), ISBNs (for books), and ArXiv IDs (for physics and computer science preprints).
Q: How does this help me with Zotero or Mendeley?
A: Once the tool finds the DOI, you can copy it and 'Add Item by Identifier' in Zotero. It saves you from manual data entry.
Q: Why can't it find the DOI in my old scanned paper?
A: The tool requires a 'text layer'. If your paper is just a fuzzy scan of a printed page, you must run it through an OCR tool before extracting the citation.
Q: Does it work on files with multiple citations?
A: Yes, it will list every valid DOI, ISBN, and ArXiv ID it finds in the first few pages of the document.
Q: Is this tool free for students?
A: Yes. We built this to help the academic community save time during the bibliography and thesis writing process.
