There are many different types of library skills that one can learn. The most basic and essential skill is probably learning how to find information in a library. This involves understanding how to use the catalog and the different types of indexes and reference materials available. Once you know how to find information, you need to be able to evaluate it for relevance and quality. This means being able to distinguish between primary and secondary sources, and understanding the difference between popular and scholarly publications. Another important skill is learning how to use Interlibrary Loan services to obtain materials from other libraries. Finally, it is also useful to know how to use various online research tools, such as databases and e-journals.
The ability to use a library is a fundamental skill for anyone engaged in academic research.
