There is a great deal of freely-available data which may be useful to add to your local VuFind® instance. Authority records from large organizations and standards bodies can help augment your index with cross-references, and Open Access publications can expand the collection that you present to your users.

This page links to a variety of open resources that you might find useful, most of which can be harvested and ingested using standard VuFind® tools. Feel free to add new sources as you find them.

• OCLC FAST - free, general purpose authority data for names, subjects and more
• MeSH - medical subject headings

• Directory of Open Access Journals (DOAJ)
• InTech Open - metadata about open access eBooks in the fields of Science, Technology and Medicine
• Networked Digital Library of Theses and Dissertations (NDLTD)
• PubMed Central OAI Service - metadata from the PubMed Central archive

• Potentially Relevant Projects - A list of complementary projects not currently consumed by core VuFind tools, but potentially worth investigating in the future.
• Linked Data / Linked Open Data - A list of resources related to and about linked data and linked open data.
• Shared Index - In the past, there was some discussion about building a shared VuFind index of open content. The project never moved past the idea stage, but if you are interested, you can join the discussion on the VUFIND-570 JIRA ticket.
