Library
In genetics, a library is an unordered collection of clones (i.e., cloned DNA from a particular organism), whose relationship to each other can be established by physical mapping. For example, you can have an E. coli library or a human DNA library. Among the types of libraries, there are genomic libraries and arrayed libraries.
