Can you help me find academic reviews for "where the sidewalk ends"?
Finding that specific poem might be fairly difficult, although there is a lot of information about “Where the Sidewalk Ends” as a whole, and about the author Shel Silverstein.
Try a search like:
"where the sidewalk ends" AND silverstein
There is some material in eBrary, too, such as the ebooks Children's Literature : A Reader's History, from Aesop to Harry Potter (particularly page 206-208) and Deconstructing Penguins : Parents, Kids, and the Bond of Reading (particularly the beginning of chapter 9).
As for material that mentions “Invisible Boy”, you could try a search like:
"where the sidewalk ends" AND "invisible boy" AND silverstein
In any of the above-mentioned databases. But beware of false hits – you’ll get some mentioning “Charlie Bone and the Invisible Boy” by Jenny Nimmo, as well. And there isn’t much there.
One example is Schultz, C. (1999, May 14). Silverstein made us believe that anything can be. The Plain Dealer, pp. 1.E-1E. We don’t have full text access to it, so you’d need to get it through Interlibrary Loan.
Please let me know if I can be of any help in using the resources.
