need all transitor and pic ic data sheet

as it is very difficult to keep on searching for page in the book is there any software were i can get maximum no of transistor and ic data sheet in a electronics book format like pdf,etc.

all the supliers provide the pdf format of the datasheets on their website for the transistors
in case you dont know the manufacturers you can use websites which have database for all components. I personally use https://www.datasheetarchive.com/
