A study by Wayne State 's Center for Urban Studies is referenced in a story about librarians' efforts to serve an increasingly diverse population. The study revealed that the Detroit area, like the rest of the country, experienced an unprecedented flow of immigration during the 1990's - the number of foreign language speakers increased by 37 percent from 1990 to 2000. Two years ago, librarians from six area libraries founded the International Roundtable to brainstorm ways to serve foreign language speakers. Libraries now stock items in languages spoken in the communities they served.
