I have a vision problem and purchased a CueCat to use to read the ISBN on the posted books. Sometimes the number the LT reader comes up with has the wrong publication date. I try to catch these errors but can't always. The book I send you will be the correct title but it may not be the exact edition date as I rely on the information from LT. All of my books are USED and most are older copies. If the date is important email me when you request the book please. Thank you. I have cats in home.
