Jason Alba of JibberJobber fame has written a book about LinkedIn titled “I’m On LinkedIn - Now What???”. The book is an excellent guide for new members and those of us who use LinkedIn only in a basic way. But it also offers something useful to the more active and experienced members of LinkedIn.

Topics covered in the book are your profile (make it true, attractive and search engine friendly), accounts & settings, connecting with others (only those known and trusted, “everyone” or something in between), degrees of separation, recommendations, jobs & hiring, LinkedIn Groups and LinkedIn Answers.

My suggestion is that if you intend to get serious about using LinkedIn as a tool for your networking then go and buy the book.

The book has a “blog behind the book” at I’m On LinkedIn - Now What???. Jason also has a category about the book at his blog, LinkedIn book.
