In the OPAC, use the icon for Lexile to find a book at a given level. Note that the search defaults to looking at the given Lexile plus or minus 50 Lexile points. Books that are marked as NPL are reflective of texts that do not fit the mathematical model used for assigning Lexile levels. Other reading levels can be searched using a number (e.g. 4) and the keyword search button. Please be aware that this will bring up all records with that number (in this case, 4) whether or not it has to do with the reading level, therefore it is only a help in the search process, it is not a direct search.
