Do you use your local library? If not, why not?
Some advantages are -
You can borrow books for free. OK, you probably knew that about books already on the shelves, but did you know you can 'suggest a purchase' of any book not in stock? There's no guarantee they'll buy it, but my local library has bought several of the books I suggested. You can also request any book that's in the library system (which includes most of mine). There's usually an admin fee of about 50p for this service.
You can read reference books. You might want to conduct story research or use to Writers' and Artists' Year book to find markets.
You can read or borrow magazines. The selection varies from branch to branch, but there will almost certainly be some which pay for fillers and the choice may include womags.
Authors earn money when their books are borrowed. It's not a huge amount and the books have to be in the right libraries to qualify and there's a cap on how much each can earn. (If you have a book available in libraries, make sure you're registered for ply.)
You can use computers for free. This includes internet access. Some libraries also allow you to print out your work for a small charge - very handy if you can't do that at home for any reason.
You can ask for help and advice. Library staff will, on request, help you find a book to suit you, help with research and assist you using their facilities and services.
There will often be talks and educational courses - including writing courses and meet the author events. Prices are usually very reasonable (I've been to a few free workshops which were excellent.)
You can borrow audiobooks, DVDs, large print, even ebooks in some cases.
The disadvantages are ...
The only one I can think of is that some of our taxes go to pay for libraries (about 6% of council tax goes on 'arts and leisure' library funding is in there somewhere). Personally I think it's great value and as we're paying anyway, we might as well use the service.
Have you voted in my poll? (up there on the right) Can you think of any other advantages of libraries, or any disadvantages?
