Communication starts within the library

I'm finding that in trying to communicate to the public, via Facebook, all of the many events and activities at my local public library, I'm not able to get up-to-date information myself from the library. Because I don't work there on a daily basis, I'm not kept informed of new events, cancellations, changes...I usually find out about them by physically walking into the library and seeing a flyer advertising a new event (that should have been emailed to me). It also happens in other areas. For instance, the administrator for the library's website is not on-site but is a city worker. This could account for the fact that the website isn't always up to date. I update the Facebook page on a daily basis according to the fall schedule of events I was emailed at the start of this project. This often takes up to an hour a day and I'm not sure the library will be willing to add this task on to a staff member when my project is over. I've offered to carry on as the administrator for an undetermined amount of time,(what was I thinking?) but the frustration of not being kept informed makes me regret my offer. It would be optimal if one person were in charge of all the library's public relations needs (flyers, press releases, Facebook, website). Because of budget, that person is non-existent. The result is that the left hand (me, the free-lancer) doesn't know what the right hand (the library) is doing.
