Average collection pending on size of school 12-48 browser bins. Normally in a quiet section of the library away from the bigger kids. Great to put units in the centre of the room & also on walls with low windows. Work out where collection will start & finish. Eg A-Z this will determine placement of units. Extra deep 300mm browser bin with a 80mm front lip for more viewing of the illustrated covers. Will need to find out amount of books in collection and divide by 70. (eg 1500 picture books = 21 bins). This will allow approx 60 – 80 books per bin. Posts can also be cut down to suit clients need eg. under a window. Many other combinations available (eg Display shelf top & 2 bins underneath).
