LAC stands for Library of American Civilization. That means the book has been preserved on Microfiche. The microfiche can be found in the periodical room and are located in the small wooden cupboard. They are organized by their LAC number. You will need the exact number to be able to find the source you are looking for. The same applies to the LEL collection, the Library of English Literature.
