“Earlier this year we released our Open Libraries wish list, which brought together four datasets to help inform our collection development priorities for Open Libraries.  After working with the wish list for a few months and reviewing our approach, we decided to make a few revisions to the ways in which we brought together the data.  Our wish list was always intended to be an iterative work-in-progress, and we are pleased to release our latest version here: https://archive.org/details/open_libraries_wish_list Download wish list now

What’s in the wish list? To create the wish list, we brought together four datasets:

1. OCLC’s list of one million most widely held books, based on holdings records of libraries worldwide;
2. Library Link’s holdings records of North American libraries, leveraging the decisions of thousands of librarians in prioritizing collections for patron use;
3. Open Syllabus Project, which has collected syllabi from the Internet to compile the most assigned books in classrooms;
4. Data about book and scholarly article citations in Wikipedia, published by the Wikimedia Foundation…”
