The final series, Library of Personal Finance, represents a portion of the materials amassed and maintained by the IFL as a research collection pertaining to personal finance education for researchers, academics, and government entities. Created in 2005, the Library contains financial literacy materials dating from 1970 to 2013. The Library documents the evolution and development of financial literacy programs and initiatives in the United States for over four decades. Many materials target specific groups such as women, children, young adults, families, those experiencing poverty or financial hardships, and adults with limited knowledge of financial concepts such as credit, loans, bankruptcy, and investments. The series is arranged in four subseries: Curricula, instructional and pedagogical materials; Conferences, symposia, and meeting records; Research papers, reports, and findings; and Audiovisual materials.

Curricula, instructional, and pedagogical materials subseries (1970-2013) make up the bulk of the entire collection and consist of records that instruct, guide, educate or train non-specialists, and professional educators in various aspects of financial literacy and money management. This subseries includes curricula for formal or self-guided courses, lesson plans, teacher guides, training manuals, workshop plans, consumer guides, handouts/handbooks, workbooks, and resource guides. The authors of the materials are a range of non-profit organizations, government organizations, for-profit entities such as banks and mortgage companies, public and private school systems, and individuals with a wide range of professional backgrounds and expertise. The curricula date from 1970 to 2013 and are arranged alphabetically by title.

The subseries Conferences, symposia, and meeting records subseries include agendas, proceedings, abstracts, presentations, programs, and promotional materials for various professional association meetings. The records date from 1982 to 2010 and are arranged alphabetically.
