Are there any books/articles about Roald Dahl's Style of writing?If so, suggest where I might find them in your reply.

Because of today's technology, academic research is
becoming easier and more available to more people every day.  Your two biggest options
for Roald Dahl research are the Internet and the good old fashioned public
library.

On the Internet, I have found Google Scholar to be
one of the best seach engines currently available for scholarly journal article
searches.  If you go to www.googlescholar.com, you can try different key word searches
that often produce full text articles which are available to view for free.  The link
below will actually take you directly to a search that was done using the keywords
[Roald]+[Dahl]+[criticism].  I usually advise students to try a few different searches
with different key words and allow your results to guide your next
search.

In the library, you are going to want to look for
Roald Dahl criticism among the non-fiction literature books.  Certainly you will find
most of his fictional works if you simply type [Roald Dahl] into a search engine.  But
if your public library is lacking in books of criticism, you might
see what collegiate libraries are available for your use.  Many public libraries in
towns and cities boasting of major universities have reciprocity with the university
library, which means you can often utilize their services for free.  If you must travel
outside your county for such a library, you may not be able to check anything out, but
certainly you could find books and photocopy necessary
information.

Good luck.
