This is a website maintained by librarians. Every week they add websites to their indexed listings with descriptions. And they happen to be very interesting websites. Search by topic or keyword.
From their website:
“Librarians’ Internet Index (LII) is a publicly-funded website and weekly newsletter serving California, the nation, and the world.
Every Thursday morning we send out our free newsletter, New This Week, which features dozens of high-quality websites carefully selected, described, and organized by our team of librarians. Topics include current events and issues, holidays and seasons, helpful tools for information users, human interest, and more.
You can subscribe to our newsletter by email or RSS, or read us on the Web. We have close to 40,000 subscribers, many from our funding state of California.
You can also search and browse our website for the best of the Web. We have over 20,000 entries, also maintained by our librarians and organized into 14 main topics and nearly 300 related topics.”
