The IHLS website has a new feature for member libraries, a Library Closing page.
You can go to this page to see what libraries are closed on a particular day. There is also a link on the page to the form to submit your own closed date(s).
Please use this if you are closed for weather, or if you're having work done on your building, or if you have staff training that will close the library. You can specify the reason and/or the hours you will be open/closed in the Comments section (please keep the comments short).
