Automate Well if you can get a text copy of his book it isn t hard to isolate all structured components like section headings IF these are diseases then your work is done sed grep awk etc If the text is unstructured you can still remove all the common words and probably isolate a list that is mostly dermatological conditions However in the latter case it may be easier to get all the pubmed hits that mention dematology and do the same technique on the abstracts This doesn t get every disease in every paper but should get those central to each paper
