QUOSA Information Manager

This QUOSA Information Manager guide is mainly for PC users. Mac users may need to consult the QUOSA User Guide for Mac for more information.


Treadwell Library is pleased to offer, to the MGH Community, QUOSA Information Manager, a desktop application for managing your personal biomedical literature collection.

What is QUOSA?

QUOSA is desktop software for searching, analyzing, monitoring, and organizing the biomedical literature and your personal PDFs, Word documents, and PowerPoint slides.

QUOSA enhances PubMed and Ovid MEDLINE searching and what you can do with the results.

PubMed/Ovid MEDLINE:
• Links to MGH and HMS eJournals. Each full-text article is retrieved separately.

PubMed/Ovid MEDLINE with QUOSA:
• Retrieves and stores all available full-text articles at one time.
• Displays the sentences where key terms are found within the citation.
• Provides easy update of a search on your schedule.

PubMed/Ovid MEDLINE:
• Searches keywords in the abstract, MEDLINE fields, and MeSH headings.

PubMed/Ovid MEDLINE with QUOSA:
• Allows for easy, powerful searching within the retrieved results.
• Suggests other key concepts that you might add to your search.

With QUOSA you can search shared drives for documents, PDFs and slides.

With QUOSA you have a seamless link between your PubMed/Ovid MEDLINE citations and your citation manager.
