In the next month or so I should have all the 1001 computer checked however I have to reference what is in the solutions to tell you where the errors are. I'm almost sure someone else has done this.
error list in Reinfeld's 1001 Combinations and Sacrifices

Part of the fun - and learning experience - in Reinfeld's 1001 Combinations and 1000 Checkmates is finding the errors on your own
Now if I could only find a list of corrections to the original edition of BCE...not the "new and semi-somewhat improved" version by GM Benko, (which still had many typos & errors according to reviews I read) but the original edition which received hundreds of corrections in GM Evans Chess Life column over many years.
Could you share the list of errors in Fred Reinfelds book 1001 Combinations and Sacrifices
