# Update Library Index The library index is a file that contains download sources for all Connected Multiomics distributed library files. An automatic update of this file will occur every 24 hours (Figure 1), so this normally doesn't require any attention. If you do wish to manually update the library index, click **Update Library Index** at the bottom of the [*Library file management page*.](broken://spaces/5WPPw051cYE3Zthy5U7m/pages/9npv9u7RcPWHiXftGkmn)

Figure 1. The date and time the library index was last updated is displayed at the bottom of the library file management page.
