| IRS990/ProgSrvcAccomActy2Grp/Desc | 0 | The Foundation also supported the Librarys efforts to help our communitys most vulnerable residents, children 0 to 6 years, in collaboration with Family Connections Library partners. Foundation funding gave teens an opportunity to learn new skills using Maker Kits in the teen-centric space known as The Union. The Foundation provided additional funding to meet needs of Library patrons beyond its walls by providing continued access to downloadable audiobooks and online databases from home via the Librarys website. |
