Here are a few sites with such services that you should claim or monitor to ensure the information listed is correct and to monitor comments or even respond to them.
1. Librarything Local
What is it?
A LibraryThing initiative, this lists libraries and bookstores around the world. Users can add events, add their favourite book stores etc. It aims to be "become the web's best, most complete source for finding bookstores and library—and for the events they throw".
How to claim
Why claim?
Unlike the other services in the list, it does not allow users to add comments, though anyone can add events. Recently Librarything released the Local Books iPhone app. This free app which is currently featured in the appstore has built in local features allowing users to find the closest bookstores and libraries that are listed in Librarything Local and access information about the place (call the phone number listed etc). This has potential to be a poor man's mobile site for libraries, unfortunately it does not allow users to search the catalogue. Though LibraryThing can easily add this but I wouldn't hold my breath as it would compete with the newly launched Library Anywhere.
2. Google maps+Google places
What is it?
You must leave in a cave not to have heard of Google maps . What you have not heard is that Googlemaps, they are now linked to the new Google places . Essentially each location on Google maps has a separate information page (click on "more information" on Googlemaps)
You can add, contact information, photos, Youtube video, opening hours, add events etc. Anyone can also add reviews.
In some ways this is an improvement on the Libraries on Google Profile idea, I blogged about last year.
Once you have claimed the location, you can even go the "local business center" service in your local profile and look at the dashboard to see how many times the pages was requested. You can add coupons to your Google map listing which customers can print out and use. Any libraries tried this?
How to claim
There are two ways to claim, but the easiest is probably via phone. Set up the contact number and request authentication. Enter the code given and you claim the site!
Why claim?
This is Google maps, the most popular maps application in the world, surely it pays to claim the information page linked to it to ensure information is accurate, being aware of the reviews posted there is also important obviously.
3. Yelp
What is it?
I covered this last year here and I wrote that it is an "online review directories (location based) that list businesses such as restaurants and users are encouraged to comment and rate such services." Do note that Yelp is available only for selected cities in the US and the UK.
Since then Yelp has started to add checkins similar to services like FourSquare
How to claim
Similar to google places, you verify you are the owner via phone.
Why claim?
Many libraries are already listed on Yelp with many reviews , see this and also listen to this interview.
4. Foursquare, Gowalla, Loopt, Brightkite etc
I've covered, the use of Foursquare by libraries.
As far as I know these location based services don't allow businesses to claim locations yet, still in the case of Foursquare, users can post comments and tips, so it's still worth monitoring.
