A lot of international library funding goes unclaimed every year, not because it doesn't exist, but because grant-seeking isn't anyone's actual job at most under-resourced libraries.
A few things worth knowing if you've never applied for funding at this level before:
You don't need a dedicated grants office.
IFLA runs its own Impact and Innovation Fund, awarding grants directly to library-led projects, and IFLA's regional divisions regularly run capacity-building initiatives in partnership with bodies like the Arab Federation for Libraries and Information. These are built for librarians without a grants department behind them.
Start with what's already documented.
IFLA's Library Map of the World hosts SDG Stories: real, documented examples of how libraries have secured support by connecting their work to the UN Sustainable Development Goals.
National associations are a real, underused starting point.
Where a national library association exists (like LIASA in South Africa), it often runs its own smaller grants, training subsidies, or conference bursaries. Where no association exists yet, IFLA's regional divisions are actively working to identify and support exactly that gap.
Building this kind of funding case from scratch is exactly what the free module, Libraries & the SDGs: Making the Case for Support, walks through.
