Cochrane and Wiley are delighted to invite you to preview the new Cochrane Library website.This preview allows you to view some of the new enhancements to the Cochrane Library before we launch. Please be aware that the site is still in development and that this is not the final version of the new Cochrane Library website; you will not have access to your saved searches and that any searches you do save on the preview site will be deleted. The purpose is to give users, and anyone training Cochrane Library users, the opportunity to explore the site before future full launch. If you identify any bugs, please let us know by using the feedback tool provided on the preview site. Some enhancements include improved article design; search expanded across all content types, including Cochrane Reviews and Protocols, CENTRAL, Editorials, Special Collections, Cochrane Clinical Answers, and other systematic reviews from Epistemonikos; a new Spanish language portal; linking between CENTRAL and Cochrane Database of Systematic Review; and, full integration of Cochrane Clinical Answers.
