Ironically we go to the library much less now that its easy to borrow ebooks with kindle and reading apps. overdrive is great. I was starting to see a future without libraries.
The computers have not only internet, but MS Office and Adobe products, and I see everything from playing games and social media to job hunting and learning being done on them. (There's even a special bank of computers with resources for job hunting downtown.)
Pretty much every day, the library holds some kind of starting a business, learning to use tech, ESL, or other kind of class.
Then there's the cultural shows (opera, movies, story readings) and free tax prep services at the central branch downtown.
The library also provides desks to work at, which are used by students (HS and college), professionals, the homeless, etc. The value of a workspace in the city is itself fairly large. I made frequent use of it when working as a freelancer. Cheaper than coworking space, cafe on site, reliable internet, etc.
And of course, the library is still a library. Their ebook collection is nowhere near the size and scope of their physical book collection. Not just the normal stuff of modern books, but fairly large archives of things like financial reports, magazine editions, etc stretching back nearly 100 years (longer in a few cases), a rare book collection, specialty archives, a collection of official government documents, and probably more Im forgetting.
That isn't stuff I need every day, most of my borrowing is (or could be) ebook/audiobook, but I think the city would be poorer without a publicly owned archive of history, even if there were digital copies available. There's something about reading a book older than your great grandparents that digital copies don't replace.
My local library now has as big of a movie rental library (for free!) as any Blockbuster back in the day, has 3D printers available for use, and office areas meant for use by startups needing some space to work.
The library has an extensive DVD collection (TV, movies, etc), CD collection (music, etc), script collection (plays and other theater), sheet music collection, music practice rooms, and of course, a foreign language collection for all the kinds of media.
Oh! And a collection of maps, covering both a large geographic area and over time so you can see the evolution of local cities. (Actually, 3 map collections -- US government Dept of Interior/USGS, other broad scale ones, and then a special collection for local ones.)
Im pretty sure I'm still forgetting things. The library system is actually kind of awe-inspiring in what they manage to collect and archive. Once you consider their relationships with local university archives, other cities, and county level systems, their total system is staggering.
I could never say enough good things about the library, and it's one of the best civic investments we make because it does so many things at once.
But based on our numbers and the community research we've done over the years, I think it's still physical materials the drive the bus. People like stuff, real stuff.
