Linkpendium is a website that proves the adage "Still waters run deep." Without a lot of hoopla and promotion, founders Karen Isaacson and Brian Leverich (the brains behind RootsWeb) have created a massive collection of nearly 5 million genealogy links—all from a California cabin "equipped with indifferently reliable indoor plumbing." In addition to accepting user submissions, the proprietors mine USGenWeb and other genealogical catchalls for resources easily missed by Googlers. Resources are arranged by geographic location (USA only) and surname (worldwide), though even the surname-specific sites are geographically located whenever possible. All in all, a worthy complement to Cyndi's List.
