There’s a lot going on today in the library. First, the new exhibit “Unidos Por la Causa: The Chicana and Chicano Experience in San Diego” officially opens. It’s located in the Reference Services area and runs through December 31. The exhibit displays photos, art and documents from the early years of the Chicano movement in San Diego.

Next up, in conjunction with the exhibit, is a lecture by Martin Gómez, city librarian of the Los Angeles Public Library. He’ll discuss “Archiving a Movement” at 7 p.m. tonight in Room LL430 of the library.

Also at 7 p.m. is the second installment of our Mark Twain Movie Nights. We’ll be showing Part I of the Ken Burns documentary Mark Twain in Room 1500 of the Student Services Building. It’s free, so all you need to bring is yourself and some popcorn!
