Daily bump

These books appear to be older with no ISBN. If you're looking to possibly purchase these books, a variey of used editions are listed in the books area of Amazon by searching for Eleanor Corwin.

Number 9 The Little Fire Engine by Wallace Wadsworth  ISBN B0007GUV2E
Benjie Engie by Louise Lawrence Devine                           ISBN B000NZZ2X2
Little Lamb’s Hat by Mary Geisler Phillips
Hickory Dickory Dock by Helen Wing
Buddy The Little Taxi by  Alf Evers                                        
Stories of the Christ Child by Mary Alice Jones
Hoppie the Hopper by Albert Baller
The Animals Train Ride by Miriam Clark Potter
Jesus and the Children by Mary Alice Jones
Hiawatha by Gridley, Marion E.

That type identifier is known as an ASIN (Amazon Standard Identification Number) and "...is a unique identification number assigned by Amazon.com and its partners for product identification within the Amazon.com organization." PBS doesn't use those for identification.

I used a title and/or author search from your list earlier here at PBS and had to select All Books to get any results. I couldn't find any that are posted. You could wish for the books, but not having ISBN numbers might make it for a very long wait--if at all. I do understand you are posting here to ask if a member might have an edition.
