Is there any book or website about ALL diseases were officially registered ever?
I doubt that there is some book that has information about all diseases. I think that one book can hold only some diseases for instance A, B, C, D and another one C, D, E, F and it can always miss some of diseases.
In order not to read all books I just want to know is there any main source in internet which most doctors use?
I need this for filtering and finding disease according its symptoms.
P.S. I have not medical education, I am just curious about it, and I want always be sure that doctors not making mistake when diagnosing.
