Publishing Student Work in the Elementary Grades

I am gathering ideas to share with an elementary school in Waltham, MA. They have a writing initiative and they are looking for good ideas for students (K-5) to publish their writing so that the writing is meaningful and purposeful. I have been gathering websites and examples and posting here:

If you have others ideas, please let me know! Thanks
