For digraphs in particular, there's Band-Jensen & Gutin's "Digraphs: Theory, Algorithms and Applications". It covers quite a bit of material.

The first edition is free to download now that the second edition is out (There's a link to the pdf on their page). Of course if you've got access to a Springerlink account, you can get the second edition instead!

Apart from being free, while I'm not sure of its popularity (especially considering it's "relatively" young), it's a weighty tome, with extensive coverage from basics to quite advanced topics and from both practical and theoretical perspectives.

The other advantage is that it's one of the few (perhaps only?) full coverage texts specifically on digraphs, rather than a being a general graph theory book with material on digraphs.
