30 Free and High Page Ranked Directories

What Wikipedia said of backlink ?

Inbound links were originally important (before the emergence of search engines) as a primary means of web navigation; today, their significance lies in search engine optimization (SEO). The number of back-links is one indication of the popularity or importance of that website or page (for example, this is used by Google to determine the PageRank of a webpage). Outside of SEO, the back-links of a webpage may be of significant personal, cultural or semantic interest: they indicate who is paying attention to that page.

Page or a site PR (Page Rank) is determined by the number of back-links to that page; and getting back-links from High Page Ranked directories makes it SWEETER.

Here are some quality backclink directories with high PR. Though submitting site to directories might be considered an old fashion SEO because there are bunch of software programs that can help you do just that in split of a second. Submitting your link to these directories wont be anything bad.
