I am currently writing a paper in which I have many topics to describe. It would not be productive to read and cite papers or even books on the topics because I just have to describe them very briefly as an introduction to some follow up topics.
For "private" use I would just use the corresponding Wikipedia articles but that is considered bad practice in academic papers.
So do you have any tips how to get credible definitions of and/or short introductions into (in my case computer science) topics without searching through dozens of papers/books for some useful/credible parts?
