Not exactly...

There are two categories of sheet music in our library:
1. Piano Street's own produced urtexts and editionsThese are our own engraved editions based on research and decisions with the aim to provide the most usable and reliable sheet music. The concept is currently refined and some improvements are going to appear within the coming year, both to the already published music and to the many new additions.
All and every of these editions are labeled "PS Urtext" or "PS Edition" both in the file name and under the composer name in the sheet music file.
2. Scanned editionsThese are scanned from 19th century or early 20th century editions which have been standardised with new titles (often translated to English) and slightly cleaned up without making any considerable changes to the music.
Many, but not all are labeled in the file link but not yet within the sheet music files.
