Official Sweepstakes Rules for Giveaways on Twitter and Facebook

NO PURCHASE NECESSARY TO ENTER OR WIN. MAKING A PURCHASE DOES NOT INCREASE YOUR CHANCES OF WINNING. This Sweepstakes (the "Sweepstakes") is sponsored by Berrett-Koehler Publishers, 235 Montgomery Street Ste 650, San Francisco, CA 94104

Sponsor may offer a similar sweepstakes from time to time. Each offer is separate. Entry into each sweepstakes is separate. The start/end time and available prize for each sweepstakes will be listed in the offer for that sweepstakes on Sponsor's Twitter page. The other terms below will apply to each sweepstakes. Many may enter; only one will win in each Sweepstakes.

1. ELIGIBILITY: Open only to legal residents of the fifty (50) United States and the District of Columbia, who are 13 years of age or older at time of entry. Employees of Sponsor, and its parent, affiliates, subsidiaries, and advertising and promotion agencies involved in this Sweepstakes, and their immediate family members (parent, child, spouse, sibling and their respective spouses, regardless of where they reside) and/or those living in the same household of each, whether or not related, are not eligible to participate in or win the Sweepstakes. Void where prohibited by law. All applicable federal, state and local laws apply.

2. HOW TO ENTER: Follow Sponsor's Twitter account and respond to any Sweepstakes offer posted by Sponsor on its Twitter page at http://www.twitter.com/berrettkoehler; by 'Re-Tweeting' or responding with a unique message including the designated #Hashtag in the manner and time period set forth in the offer (the "Entry Period"). Limit one (1) entry per unique twitter account and per person per Sweepstakes. Entries generated by script, macro or other automated means are void, as are entries that are illegible, garbled, incomplete or that contain errors. Normal time, toll, connection and usage rates, if any, charged by your Internet service provider will apply. All entries become the property of the Sponsor. No other entry method will be accepted.

3. WINNER SELECTION: One (1) Winner will be selected in each Sweepstakes by random drawing from amongst all eligible entries received. Proof of transmission is not proof of receipt. Sponsor's computer is the official time-keeping device for the Sweepstakes and determines the order of receipt of entries. All decisions of the Sponsor are final and binding with respect to all matters related to the Sweepstakes.

4. WINNER NOTIFICATION/VALIDATION: The Winner will be notified via @mention and asked for an eligible mailing address via Direct Message. If winner is a minor, all documents must be signed by parent or legal guardian. Noncompliance within this time period, with these Official Rules or the return of any prize/prize notification may result in disqualification and, at Sponsor's discretion, an alternate potential winner may be selected by Sponsor based upon Sponsor's records of the next fastest entry received. Prizes will be fulfilled approximately 2-4 weeks after winner validation. Any winner later determined to be ineligible may be required to return his/her prize. Any taxes on prize are the responsibility of the winner.

5. PRIZE AND ODDS: One (1) prize is available: The Book mentioned in the Sweepstakes offer (Estimated Retail Value between $5.00 and $50.00, depending on the book). No transfer, substitution or cash redemption will be awarded in lieu of stated prize except by Sponsor who reserves the right to substitute a prize (or portion thereof) of comparable or greater value, in its sole discretion, if the advertised prize becomes unavailable. All prize details are at the sole discretion of the Sponsor. Odds of winning depend on number and timing of entries in each Sweepstakes.

6. GENERAL RULES: Acceptance of prize constitutes permission to the Sponsor and its designees to use each winner's name, city, state, likeness, voice, biographical information and statements for purposes of advertising, promotion and publicity in any and all media, now or hereafter known, throughout the world in perpetuity without additional compensation, notification or permission, unless prohibited by law. By participating, entrant (i) agrees to release and hold Sponsor, and its parent, affiliates, subsidiaries, and advertising and promotion agencies, and each of their respective directors, officers, employees and assigns (collectively, the "Released Parties"), harmless against any and all claims and liability arising in whole or in part, directly or indirectly, out of participation in the Sweepstakes or misuse, nonuse or use of any prize; (ii) waives all rights to claim punitive, incidental and consequential damages, attorney fees or any damages other than actual out-of-pocket costs incurred to enter; and (iii) agrees to be bound by these Official Rules.

Sponsor reserves the right in its sole discretion, to cancel, suspend or modify the Sweepstakes, or to disqualify any implicated entrant(s), (and their entries) if any fraud, virus, actions by entrants, technical or other error or problem, or any other occurrence corrupts or affects the administration, integrity, security, or proper play of the Sweepstakes, as determined by Sponsor in its sole discretion.
