تحقیق یقینا ایک دقت طلب اور محنت کا کام ہےاور کیا ہو کہ اگر یہ دقت طلب کام مشقت وافر سے لکھنے کے بعد چند تحقیقی اصول کا خیال نہ رکھنے کی بنا پر بھونڈا، بے ترتیب، معلوم ہو۔ اس لئے تحقیق کے اصول و مبادی ہر محقق کے ذہن نشین ہونا اتنا ہی اہمیت رکھتا ہے جتنا کہ اصل تحقیق کے نکات۔ اردو زبان میں تحقیق اور اصول تحقیق پر اول اول بہت کم لکھا گیا اس کی شاید ایک وجہ یہ بھی ہو کہ اردو زبان کی عمر کم ہے ، کیوں کہ جس زمانے میں اردو پڑھنے ،سننے ااور لکھنے کے قابل ہوئی اس زمانے میں چھاپے خانوں کا ایجاد ہو چکا تھا، اس لئے اصول تحقیق پر بہت زیادہ نہیں لکھا گیا ۔ چند کتابیں تھیں جن کو سامنے رکھ کر لوگ تحقیق کا کام کرتے تھے۔ مگر ہر زمانے میں کچھ نہ کچھ اصولوں میں تبدیلی آتی رہتی ہے اس لئے ان نئے اصولوں کو مرتب کرنے کے لئے نئی کتاب یا نئے ایڈیشن کی ضرورت پڑتی ہے ۔ گیان چند کی یہ کتاب بھی ان نئے تحقیقی طریق کار کی بھرپائی کے لئے ایک بہترین کتاب ہے جس میں تحقیق کے اصول کو بہت ہی مفصل طریقے سے بیان کیا گیا ہے کہ ہم تحقیق کو کیسے شروع کریں، اس میں کن باتوں کو ملحوظ ررکھیں، مواد کیسے فراہم کریں، مطالعہ کیسے کریں اور نوٹ کیسے بنائیں ۔ زبان و بیان اور اس کے علاوہ بھی چیزیں جو ضروری ہیں ۔ تحقیق کے طالب علموں کے لئے یہ کتاب یقینا ایک بہتریں مددگار کتاب ہے اور ہر ایک کو اس کا مطالعہ ضروری ہے۔ تاکہ وہ اپنی تحقیق کو سانٹفک طریقے سے انجام دے پائیں۔
