Because of that often needed long time to find a system here is an Excel sheet with all systems, sectors and sector blocks. There is a sort function over all columns. It is a quick reference list for me and much easier to use as large star maps.
Maybe it will help some of you, too.
Here is the download, its is just a simple excel file:
I modified the front page to show a drop down box for the system to be searched for and the sector and sector block are filled in for ease of use. Don't flame me for the site to download from, it's all I have available.
