Take Control Books is offering its wide selection of electronic Mac titles at a 50 per cent discount to mark its third anniversary.

The sale extends through until next week, 13 November. The discount applies across the publisher's extensive range of titles, covering everything from system maintenance to .Mac optimisation.

In order to qualify for the discount, potential customers must access the store using this link only.

Take Control publisher, veteran Mac writer Adam Engst, said: "It's been a fun three years, as we've sold 89,000 copies of 44 titles. We started Take Control Books back in 2003 with the goal of helping normal users make the most of their Macs, a goal we meet with every eBook sold."

Take Control is a spin-off of TidBits Electronic Publishing, which has been publishing information about the Mac since 1990.
