This product includes four types of "Library Sign Out" sheets to help keep track of the books in your class library. Depending on how you have your library organized, you can use whichever sheet works for your class library. I print about 30 of these at the beginning of the year and put them on a clipboard in my class with a pen attached. The students choose a book, sign it out, and sign it back in when they are done. This works great if you use the DAILY 5 for you reading block. As a bonus I also included a sign I put on a box in the library so students can place any damaged books there. This saves me the headache of students coming up to me and telling me, "this book has pages falling out", etc.
