I believe it all depends on accreditation. With Library Sciences, depending on where you want to use it, you need to be sure that the American Library Association acknowledges the degree plan. Without an ALA, you may not get a job in k12 schools. In Texas, only two or three universities provide online ALA credits: Texas Women’s University, North Texas U, and UT Austin. That’s just Texas though. You can get more information on ALA’s website: link
