The American Library Association has published the 2008 edition of the ALA-APA Salary Survey: Librarian—Public and Academic.
Here's an excerpt from the press release ("Librarian Salary Survey Reports Mean Librarian Salary Up 2 Percent to $58,960 in 2008"):
Analysis of data from more than 1,010 public and academic libraries showed the mean salary for librarians with ALA-accredited Master’s Degrees reported increased 2 percent from 2007, up $1,151 to $57,809. The median ALA MLS salary was $53,251 and salaries ranged from $22,000 to $331,200.
Note that the press release headline says that the mean salary is "$58,960," while the first paragraph of the press release says it's "$57,809." According to the press release for the 2007 edition, the "mean salary for librarians with ALA-accredited Master’s Degrees reported increased 2.8 percent from 2006, up $1,550 to $57,809." The 2007 mean salary ($57,809) added to the 2008 $1,151 increase gives $58,960.
