Listservs/Discussion Groups

This listserv is probably one of the best resources for school librarians. I used this tool as one of my Independent Learning Activity Choices, and got a huge number of tools and resources from it. I heard about this listserv in my School Media class and I use it every single day. It's strength is the vast, vast amount of information and expertise that is available from it. The only downside is it's a bit overwhelming and amount of emails is almost impossible to read every day.

This is a listserv for school librarians, public librarians, and academic librarians to discuss information literacy. I haven't subscribed to this listserv, so I don't know what it's like, but I like the idea of librarians from different areas discussing information literacy and I'm thinking about subscribing to this listserv. I found this tool simply by searching for "school library listservs" on Google. Because I haven't participated in the listserv, I don't know about it's strengths and weaknesses, but I imagine they're similar to LM_NET.
