Auto Text Summarization
First off for Paper, I recommend:
1- Recent automatic text summarization techniques: a survey by M.Gambhir and V.Gupta
2- A Survey of Text Summarization Techniques, A.Nenkova  
As for tools for Python, I suggest taking a look at these tools:

The Conqueror: NLTK  
The Prince: TextBlob
The Mercenary: Stanford CoreNLP
The Usurper: spaCy
The Admiral: gensim
First off learn about different kinds of summarizations and what suits you best. Also, remember to make sure you have a proper preprocessing tool for the language you are targeting as this is very important for the quality of your summarizer.
I have decided to develop a Auto Text Summarization Tool using Python/Django. 
Can someone please recommend books or articles on how to get started? 
Is there any open source algorithm or made project in the Auto Text Summarization so that I can gain the idea? 
Also, would you like to suggest me the new challenging FYP for me in Django/Python?
