since the IBM sort algorithms are patented nobody from IBM will You tell anything about them
that' s being picky ( on the IBM side ), since they are patented it does not harm IBM IP rights You knowing about them

if You are eager to learn about sorting techniques a starting point could be
Donald Knuth Art of Computer Programming, Volume 3: Sorting and Searching

if You are really curious about IBM or SYNCSORT ways
You might search here
http://www.uspto.gov/patents/process/search/
the USPTO Patent Full-Text and Image Database (PatFT)

a search for IBM sort returned about 10000 hits

it' s amazing how much info You can extract from there ( the patent' s database )

the only boring thing is that it' all written in legalese, and You will have to discard about 50% of the text
cheers

When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort
