Not listed or organized in a catalog or inventory.
The library has many uncataloged books that need to be organized.
Uncataloged → It is formed from "un-" (meaning not) and "cataloged" (from the root "catalog" which comes from the Greek "kata" meaning down and "legein" meaning to gather or to read). The word "uncataloged" means not organized or listed in a catalog.
Think of 'not' ('un-') being applied to something that is 'gathered' or 'listed' ('cataloged'). This helps you remember that 'uncataloged' refers to items that are not organized or listed.
