Directory list? What to include

I am making a list of Directories/ Resources, for say article directories, High pagerank site directories, Press release, etc. {for SEO people in particular}

For other marketers to use.
What should i include in this list ? besides these 2

Directory name
URL of directory.
Page Rank of each site


What other things?
and would this be best in an Excel grid? or a PDF report style?

 

Backlinks, traffic, year started.

 

Simple format to make directory list. -
1) URL 2) Page rank 3) Username 4) Approved link
Directory is very useful to make backlinks.
Must be local and high page rank directories. its always works.

 

Well what i love when i go to dir lists is the proper sortings according to pr,date,and alphabetical orders plus a simple and easily scrolling list.
Also if there is a submit tab in front of each dir which shows you have previously submitted in it provides great ease

 

You can also indicate if its a Paid, Free or wants Reciprocal links etc.

 

Add to the rest here, a brief description of the directory and what genre/niche' the directory is in.

 

Be sure to add a credit to the places where you obtained all the directories from...

 

I think it should be:
Name
Type
URL
Page Rank
Link popularity
Archive
Price.
