Hello, Sobreira, welcome to Wikisource! Thanks for your interest in the project; we hope you'll enjoy the community and your work here.
You'll find an (incomplete) index of our works listed at Wikisource:Works, although for very broad categories like poetry you may wish to look at the categories like Category:Poems instead.
Please take a glance at our help pages (especially Adding texts and Wikisource's style guide). Most questions and discussions about the community are in the Scriptorium.
The Community Portal lists tasks you can help with if you wish. If you have any questions, feel free to contact me on my talk page! John Vandenberg (chat) 23:05, 20 April 2008 (UTC)
