books.google

 أداة من جوجل تبحث في النصوص الكاملة للكتب التي يقوم جوجل بمسحها وتخزينها في قاعدة بياناته الرقمية. هذه الخدمة كانت سابقاً تعرف باسم طباعة جوجل Google Print حينما قدمت في معرض فرانكفورت للكتاب في أكتوبر 2004. أثناء البحث في موقع جوجل، حينما تكون كلمة البحث المدخلة مقاربة يقوم الموقع بعرض حتى ثلاث نتائج من بحث كتب جوجل. بالطبع يمكن للمستخدم أن يبحث عن كتب معينة في بحث كتب جوجل. بعد النقر على نتيجة بحث الكتب، تظهر واجهة من خلالها يستطيع المستخدم عرض صفحات من الكتاب بالإضافة إلى إعلانات تجارية لها علاقة بالموضوع وروابط لموقع الناشر والبائع على شبكة الإنترنت. نظراً لاعتبارات أمنية، يقوم جوجل بتحديد عدد الصفحات القابلة للعرض ويمنع أي محاولات لطباعة الصفحة أو نسخها نصياً حين خضوع النص لحقوق ملكية بالاعتماد على تتبع المستخدم.

On January 1, 2010 it merged with the Librarians' Internet Index to become ipl2. It ceased operations completely on June 30, 2015.

As of 2020 IPL has been purchased by Barnes and Noble Education and the above layout has been replaced, it now resembles an essay repository for students, also it now has a paywall on its essay offerings.
