"To create a new item, click "New" or "Upload" above. There are no items to show in this view of the document library."
The above text is displayed when a Document Library is empty. Today I needed to change it. I had done this once before and forget so I'm blogging about it so I can find it next time. The text comes from the core.resx resource file, located in 12\RESOURCES. It's divided up into four resources; just open the resource file in any text editor and search for "noitemsinview_doclibrary", and you'll find the strings. Just replace the strings with your text or delete them all together.
Here a link explaining with more details.
