In case you missed your opportunity to proofread the Digital Library in March, another book is now available through the Distributed Proofreaders project. This month’s title is Catholic Colonization in Minnesota, a 19th-century pamphlet full of advice about opportunities for Catholics in Minnesota. If you have the time, stop by and help preserve a little piece of history. If you don’t get there quickly enough this month, don’t worry: more titles are on the way.
