Residents who want to learn more about downloading electronic books for free are invited to attend a workshop at the public library on Jan. 28. Librarians will guide participants in how to download e-books from the library’s website to the Apple iPad, Amazon Kindle, and Barnes and Noble’s Nook and Nook Color. The free workshop will be broken into two sessions: one at 7 p.m. focused on the Kindle or iPad, and at 8 p.m. on the Nook or Nook Color. Meanwhile, the library will hold a special program on “Terrorism and the 1993 World Trade Center Bombing” on Jan. 17 at 7 p.m. Retired FBI agent William A. Gavin, who directed the investigation into the 1993 bombing, will offer a behind-the-scenes look at that attack with a focus on its relationship to the subsequent 2001 terrorist attacks. The event is sponsored by the Friends of the Burlington Public Library. The Friends group is also inviting the public to its annual meeting on Monday at 7 p.m. at the library. Following the brief business portion of the meeting, Jane McInnich, a Burlington resident who is a chocolatier, will offer a presentation on chocolate tasting, providing samples to participants.
