My local library observes "coffee shop rules." People sit with their laptops and take phone calls from wherever they receive them. Even the librarians are loud. It's fucking bullshit.
I'd like to slap people who say they aren't relevant or useful, but I don't have that much slap in me. As physical books become more of an out-of-date phenomenon (thanks to the Kindles and nooks and tablets and Wikipedias and such,) people are going to see the necessity of libraries as silly.
It's why you see "libraries should be hackerspaces!" make the rounds in blogs (and at least one library in the northeast is doing this.) I went to a new library up the road recently that had as much floorspace dedicated to audiobooks, DVDs, and CDs as it did to physical books.
I've recently read someone say that libraries provide one thing that no other building does: a place where anyone can work or study with zero pressure to spend money. That addresses your comment about "coffee shop rules."
While I still want to slap people who think libraries are irrelevant, they absolutely can't stay as just a place to check out books. Owning an internet-capable device is a lot more affordable than owning a recent encyclopedia, so computer courses are a natural thing for libraries to provide. I definitely like hackerspaces in adjacent floorspace. Chicago libraries allow residents to check out museum passes (though, access to this has dwindled quite a bit.) I believe some libraries allow patrons to check out iPads; I'd love to see an extensive ereader loaning program, though it'd require publishing companies to be less of a sack of assholes about ebook ToS.
As somebody who once did work experience here: http://tinyurl.com/d28gxz4, I was a bit puzzled to be in an almost bookless library.
I suspect "coffee shop rules" are the future of libraries.
Luckily there are lots of books, I haven't seen them removing any.
Why is this lucky? Are the books being used?
