I first got involved with the intellectual freedom committee (IFC) by presenting on the Ain`t on the G&M panel at the BCLA conference.
Here`s the rationale behind presenting lesser known materials, often from small independent publishers (from the IFC page):
For the past three years, members of the BCLA Intellectual Freedom Committee and other librarians committed to building diverse collections in public libraries gave an introduction to the value of seeking quirky, less-mainstream and less-hyped materials for patrons. In this session, books, DVDs and videos are introduced at breakneck speed! None of the materials will ever appear on a bestseller list or as an Oprah pick, but we believe the public library has a much more important function than just providing commercially-driven materials.
