Results are too basic
You've run a search, but all the resulting articles are very short, don't give you enough detail and are a bit too basic.
When resulting articles are very short and basic, they have usually come from trade journals or magazines, and not from academic journals. This problem is often overcome by selecting a database that includes peer-reviewed journals and limiting your search within the database to exclude magazines. There's often a box you can tick on the database search screen that allows you to limit your search in this way.
Use your Subject Guide to make sure you are searching the best resources for the job.
There are two main types of journals:
Peer-reviewed journals have an editorial board of subject experts who approve content for publication. This means you are reading quality information. Peer-reviewed articles are often long (over five pages) and may include current theories, models and research.
The trade press usually consists of magazines. The articles in these journals will be much shorter and more "newsy".
