These are the best databases (available at Malmö University) for finding information in computer science.
Unlike a quick search in Google, the databases require you to develop a search strategy in order to carry out a search. It is important to look for settings like: "Search tips", "Turorials", "Subject Terms" or "Help" before you enter your search. Some databases have a Thesaurus (list of subject terms, usually arranged alphabetically) from which you can choose your keywords (search terms).
Keeping a logbook or making a mind map for you search strategy is a good idea!
