Pete Kenny, of FBDD & Molecular Design fame, has generously uploaded 13 slide presentations on SlideShare. Several of these directly relate to fragment library design and screening, while others are broader overviews of drug discovery or touch on important topics such as lipophilicity and hydrogen bonding. Pete wrote recently about the danger of "correlation inflation," and you'll find a slide show on that too.
The presentations are ornamented with photos collected from Pete's extensive travels and suffused with his trademark sense of humor: where else can you see Carl von Clausewitz expounding on covalency?
There's a wealth of information and it's all free, so check it out!
