The document summarizes Washington University Libraries' process of converting their 12,000 volume print reference collection to digital. They were given a mandate to reduce the print reference collection by 90% and a budget of $50,000. Librarians identified the most important print titles and searched for electronic counterparts. They learned that ebook pricing varies and collections are often better than individual ebooks. The process involved subject librarians identifying titles to keep in print or move to other locations, evaluating standing order titles for conversion to electronic, and addressing issues in converting over 11,000 volumes to digital.
