Learning VuFind® is a free introductory eBook, available in PDF from the releases page. If you want to learn about the history and functionality of the software, this is the best available starting point.
The VuFind® Project Management Committee is developing a program which will allow publishers to use an official “This Book Supports VuFind®” logo on books that meet the PMC's approval, if they donate a portion of proceeds to support the project. Please reach out to info@vufind.org if you are interested in participating.
A partial bibliography of articles and book chapters referencing VuFind® can be found in the VuFind® Zotero Group.
