7 <h1>Item types management</h1>
8 <p>You can define as many item types as you want.</p>
10 <p>The item types are the "categories" into which your library items fall. For instance, you probably want to have videocassettes in a different category from non-fiction books, and mysteries in a different category from children's picture books. If you already are using a commercial ILS, you almost certainly already have all of your materials divided up into such categories. Now you need to tell Koha what your categories are.</p>
12 <p>The itemtype code is limited to four characters. This code is rarely displayed by Koha; instead the description of the type will be what users see.</p>
14 <p>"Rental charge" is any amount you might charge to users for borrowing items of a certain type (like videos).</p>
16 <p>"Renewals allowed" indicates how many times an items of this type may be renewed.</p>
18 <p>Item types are useful for many things, and <b>very</b> important in controlling how Koha works :</p>
20 <li>Patrons can search on item types</li>
21 <li>Issuing rules are set for item types (and for patron types / libraries)</li>
23 <p>Setting up item types is one of the first things you should do after installing the Koha software.</p>
