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

• PubMed Central OAI Service - metadata from the PubMed Central archive

There has been some discussion about building a shared VuFind index of open content. This is an ambitious project that is currently just in the idea stage. Feel free to comment on the JIRA ticket if you have thoughts on the subject.
