Hi Prabo, Welcome to LibriVox! We're glad that you are enthusiastic about recording.
The first thing you'll want to do is to complete and get an OK on LibriVox's one-minute test to check the technical specifications of your recording files. This is not an audition. It's a requirement to simply confirm that your recording "specs" meet LibriVox requirements. Please post your one-minute test in the "Listeners Wanted" thread and an experienced LibriVoxer will have a listen and check the specs for you.
Here is the link to the one-minute test: https://wiki.librivox.org/index.php?title=1-Minute_Test.
Here is the link to the "Listener's Wanted" thread: viewforum.php?f=21
When your one-minute test has been ok'd, you can look in the forum threads that say "Readers Wanted" to find ongoing projects that you can join to read poems, short stories, chapters of books, and so on. Or you can come back to the Short Nonfiction Collection. The SNF does not have assigned readings. You get to pick what you want to read. You'll find suggestions on where to find public domain nonfiction to read in the first post for this volume of the SNF
Best wishes,
Sue Anderson, Book Coordinator (BC)
