CLIO, the library's catalog, is one resource for conducting a broad search of resources held by Barnard and Columbia Libraries.
These search results will include ebooks, books, archival material finding aids, articles, dissertations, and newspaper articles. You can refine search results to get items that more closely align with your topic.
Try broad searches:
Find books and ebooks on a broad topic and search chapters on more specific subjects within the broader topic. Find more resources through sources cited within chapters. See examples of ephemera.
