As I've already reviewed Informants 113, 114 and 115 when they come out in book form, I won't repeat here what I said though you can find the reviews of each by clicking on the links above. My conclusion about those volumes, and with the Informant in general, now that the publishers have revitalized this venerable series, is positive. They aren't for everyone, but for strong club players - around 1800-1900 and up - the volumes can be both instructive and entertaining.
If it sounds interesting and you haven't already purchased those volumes, this is an excellent way to do it. The price for buying the three-pack on disc is considerably less than the cost for getting each Informant one volume at a time. The books run about $38 a pop, while this three-pack goes for about $64 from the publisher's site. Add to the savings the convenience of being able to examine the games (and all the other sections too) using ChessBase, Chess Assistant a PGN viewer or even the proprietary Informant format and it's an all-around good deal.
So if you're interested in the Informant and don't yet have these issues, it's definitely worth considering - especially for U.S. buyers, who can get it here for $57 (plus shipping). Highly recommended (for stronger/more ambitious club players, and up).
