The average household would be willing and able to donate [to public libraries] between $31.7 and $38.3 US dollars annually, resulting in a total donation for Minnesota’s approximately 2,061,882 households of $65.4 to $79.0 million annually.
There is no statistically significant difference between men and women on the question of whether public library support should be increased, remain the same, or be decreased, although in both cases the vast majority felt that public library support should stay the same or increase.
In 2004 Carnegie Library of Pittsburgh supported more than 900 jobs and $80 million in economic output in Allegheny County through its operations and renovations. Even without the additional impact of these renovations, the library can be expected to sustain more than 700 jobs and more than $63 million in economic output in Allegheny County annually. (p.2)
The Library is associated with $16 million in net new spending in Seattle in its first year of operations--equal to $80 million for 5 years, $160 million for 10 years, or $320 million over a 20-year period. Nearby businesses report increases in spending associated with visitors to the Central Library. Increases in the use of Library resources contributes to learning, literacy, business productivity, personal and professional developments, and individual livelihood.
More than 2.3 million tourists are expected to visit the Central Library during its first year of operation, an increase of more than 250% compared to the prior year. Approximately 30% of these visitors--725,000 individuals--are projected to be out-of-town visitors, coming from the Puget Sound region, other states, or other countries. The Library is drawing greater numbers of visitors from a larger radius; these increases in activity drive the economic benefits the Library brings to Seattle. A 1% increase in annual visitors to King County creates $1 billion in new spending statewide over a 25 year period.
... 92% of those polled felt that public libraries were a good investment for their tax dollars.

The B/C (Availability) of Florida's public libraries is 10.8 to 1 where the benefit to the state in terms of availability of Florida's public libraries is the total cost to use alternatives of $4.3 billion divided by the cost of $668 millions (includes cost of multi-type cooperative support to public libraries). The B/C (REMI Wages) is 7.5 to 1, where the benefit to the state in terms of wages is $21.8 billion and the cost is $2.9 billion. The B/C (REMI GRP) is 5.1 to 1, where the benefit to the state in terms of GRP output is $14.9 billion and the cost is $2.9 billion.
Overall, Florida's public libraries return $8.32 for every $1.00 from all sources. The total revenue investment in Florida's public libraries was $661.5 million in 2008.
