From a post by Teresa F. on the VLA Listserv:
Non-profits across the country are getting donations from web searches made through GoodSearch (a Yahoo search engine)and online purchases made through GoodShop (which connects to regular online retailers). The trick is getting your patrons to go through the GoodSearch/GoodShop sites to search or shop.
A number of Vermont organizations are already listed as beneficiaries. If your organization does not care to be listed, perhaps your own searches and purchases could benefit the charity of your choice. Go to http://www.goodsearch.com for more information, including coverage of the service by national media, lists of nonprofits currently enrolled, FAQs, etc. The donation check comes just once a year in December, for activity from the previous October through September.
If it were me, I’d change the library default browser to this browser and explain to patrons why to use it…it may even carry over into their home searching.
