If you were thinking of a trip to the library on Thursday in Sussex County – you’ll probably be out of luck. Most public libraries will be closed on May 3 for the annual Delaware/Maryland Library Association Conference. This is continuing education and professional staff development for the four County-owned libraries and 11 independent libraries. The County-owned libraries – except Milton – will be closed. Milton will be open from 10 to 5pm on the 3rd. All libraries will be open Friday at their regular times.
