Get a flat open-face bookshelf. You can purchase those bookshelves from authorized retailers, such as One Step Ahead or Mercantila (see Resources). The flat, open-face nature of the stand will allow the children to easily locate and replace books.
Categorize your books by topics. Write a list of educational topics that are important to your preschool class. Organize preschool books by transportation, animals, colors, shapes, numbers and other topics. For example, place all books that relate to colors and shapes together. The children will know where to go when looking for books, such as "A Rainbow of my Own" by Don Freeman or "So Many Circles, So Many Shapes" by Tana Hoban.
Have a section for books that are related to a specific subject you are teaching. For example, if the children are learning about birds, place all the books that relate to the subject in a special corner. Also create a section for the children's favorite characters, such as Franklin, Curious Georges or Sid the Science Kid. Alternate the themes depending on the lesson you are teaching.
Make a label for each category. Use a paper and a marker to write a description of the category. Add a picture, as children work well with visuals. Tape the label where you will place the books. For example, for the animal books category, write "Animals," and add a magazine image of a lion or a giraffe.
Let your preschool students know how you classify the books and ask for their help in maintaining the library organized and clean. This will help the children respect and take good care of the books and improve their reading skills, as they will start matching the labels with the corresponding books.
