There's no phone number, because we're all volunteers from all over the world - there is no central office.
Over the past 13-plus years, a system has developed which makes the recording and cataloging process as smooth as possible. Shortcuts are always risky, because the usually cause problems later on. I'd say the most basic, down-and-dirty sequence to record:
1. Make sure your technical settings are correct. The easiest way to do this is via the
1-minute test.
2. Find a suitable text. Ideally, it would be a text available online somewhere, and without any restrictions placed on it. It has to be public domain in the USA - so a scan of a text published in 1923 or earlier, or a text in html/plain text format
that clearly states it has not been edited from a PD edition. (The Rule of St. Benedict has been recorded for LibriVox already; it's here:
https://librivox.org/author/5764 You're welcome to do another version of it if you like, and the text used for these would be acceptable again.)
3. Find a project to record in. If the works you're thinking about are short (70 minutes or less), the quickest and easiest way is to submit them to the Short NonFiction Collection. Here's a link to the current one:
viewtopic.php?f=28&t=73089 It is cataloged after 20 submissions, and the link will change when that happens.
If the work is longer than 70 minutes, it would have to be set up as a new project with a Book Coordinator. Usually BCs choose their own projects to coordinate, so we'd either have to have someone volunteer to do that for you, or you'd have to do it yourself, which takes a bit of learning. (We don't recommend people brand new to LibriVox to become book coordinators.) Here's a link to the wiki explaining what a BC does:

4. Record the sections, upload them, and add them to the project.
5. Make any needed edits.
Once all sections are in and proof-listened and OK'd, the project would be cataloged by the meta-coordinator (MC).
Hope this helps. For further reading, here's a page on how LibriVox works:
