Sanskrit Documents website (link given at the bottom) is a compilation of Sanskrit Documents in Devanagari display and transliteration format. In addition to the sanskrit texts, you will find here various tools for learning Sanskrit such as the Online Sanskrit Dictionary, Sanskrit Tutorials, Sanskrit Pronunciation guides, and software for learning Sanskrit and producing documents in Devanagari and Roman formats, and much more. I could even find an archive of Sanskrit news in All India Radio which you can listen to sharpen your sanskrit listening and understanding skills. You can generate display in Devanagari or other scripts using the web-interface. There is even a resource for sanskrit tattoos!
For the sanskrit scholars, there is a long list of Sanskrit documents available elsewhere, hundreds of scanned books, and audio files on the internet which you can access from the site. If you have time to spare, please consider volunteering to proofread the texts. You may join the email-based lively discussions or just leave a note in the guest book to mark your presence.
