I used to always put up an author study each month on a large bulletin board. I somehow got away from that and try to keep bulletin boards up during the year that are more interactive and that I don't have to change(my favorite kind)...like the calendar, US map, daily five, etc.
I bought a great frame at Target that was designed for album covers. It has hinges and the glass is really plastic. I get nervous with kids. Here are the two that I have designed so far. The pages are very easy to make and take up no space!
I am incorporating the authors with my listening center. I got two of Shel's books on Itunes and set the books out with the CD's that I made. It is great for fluency and The Daily Five.
You can see the frame at the listening center
My second author is Andrew Clements and I just got "No Talking: on CD.
