aunt ingrid if you type up a list of the books and author, year of print or publish, publisher etc. I will look them all up for you and send you a list back, can give you ideas of values, you can have my login and list them in my store for 30 days if you wish, gives them a bit longer exposure, or i can send link so you can look them up, do a spreadsheet and i will check it over for you, quicker if you do it there, no lists required just bookmark the tabs in the search engine i will send you link for, specialist books can fetch good prices and certain authors
