AUSTIN, Texas (AP) - A proposed shield law for journalists is headed to Gov. Rick Perry's desk after final approval in the Texas House.

The Free Flow of Information Act was unanimously approved Thursday, with the House accepting minor Senate changes and ending years of debate in both chambers. Similar proposals were shot down in 2005 and 2007.

The bill gives reporters limited protections from revealing confidential sources, notes and tapes in court. Journalists say it will encourage whistle-blowers to come forward.

The measure needs Perry's signature to become law. His office hasn't taken a firm position on the latest version.

There is some form of a shield law for journalists in 36 states and the District of Columbia.
