# Library Manager

{% hint style="info" %}
Library Manager requires a Pro License, and is currently only available on macOS.
{% endhint %}

From Canister for Mac `24.2`, it's possible to manage library inventory without leaving the Canister interface.

The Library Manager is accessed via the hamburger menu:

Simply drag and drop between your Drive, tape slots, and Mail Slot:

## Mail Slots

Most tape libraries feature at least one mail slot. A mail slot allows tapes to be removed and transported without powering down the device. For convenience, Canister's Library Manager shows mail slots alongside regular tape slots.

## Hardware Support

{% hint style="info" %}
Canister doesn't currently support multi-drive tape libraries.
{% endhint %}

Library Manager is validated for use with the following models:

* [Magstor M2000](https://magstor.com/collections/m2000-tape-libraries)
* Qualstar Q24
* BDT Flexstor II
* Quantum Superloader 3

As most libraries are using the same underlying hardware from BDT, there's a good chance tape libraries from other vendors work just as well with Canister. Feel free to reach out when in doubt, or if you'd like to share that your specific tape library model also works.&#x20;

HPE tape libraries are not (yet) supported.
