For website on Padre Pio I visit:
caccioppoli (dot) com

It is very extensive on life of Padre Pio with photos written by Giuseppe Caccioppoli

For books on Padre Pio, I search on
Isidore (dot) co
Search "Padre Pio"

Especially books titled Encounters with a Spiritual daughter from Pietrelcina written by Graziella Mandato.

On St Faustina Kowalska, I cannot thank her enough for letting me know her daily life on Diary of St Faustina. It is one of the first Saints' Books I read and know of, and the others are writings of St Therese of Lisieux (her Autobiography, Story of a Soul), and writings of St John of the Cross (Spiritual Canticle of the Bridegroom Christ). They are indeed my favorite books.

On St Anthony Mary Claret, I cannot thank him enough, because of his Autobiography, I read and collect all writings of the saints and lives of the saints he read.

You are very blessed to have visited San Giovanni Rotondo, and St Padre Pio's cell. I would like to visit there too if I have the chance.

I also have St Padre Pio's image in my room, by my bedside. It is a blessing. 

Sorry for the late reply.

Happy belated birthday

I would feel St Anthony Mary Claret was the most influential in my path of perfection, because he listed all the Saints' Books he read in his Autobiography, and I try to find the books on archive dot org and they were available. I was elated. Maybe I can become more like him by reading the same books he read.

St Faustina and her diary was one of the first Saints' Books I read, back then they were excerpts, but now it is available in full book as a PDF. I immediately read it cover to cover.

As to finding a spiritual director, I would see that the saints are the best in being a guide/director for that matter, take for example St Padre Pio, you can be his spiritual son/daughter, by praying to him and asking him, so that you may be one of his spiritual children. From then on, you can pray to St Padre Pio more often and feel his guidance and protection throughout your life.

Just my 2 cents 

On Catholic reading, try to narrow your reading to writings of the saints and lives of the saints. On writings of the saints I would suggest authors like St Anthony Mary Claret (Autobiography of St Anthony Mary Claret), St Faustina Kowalska (Diary of St Faustina). If you like to read writings of a priest, St Anthony Mary Claret is a priest. For lives of the saints I would suggest Life of St Catherine of Sienna by Blessed Raymond of Capua, or Life of St Anthony of Egypt by St Athanasius. If you would just finish one book, like the Diary of St Faustina out of 3500 books, it would benefit your soul much if it is written by a saint, even finishing just one book is an accomplishment. God Bless. I learned it from the Autobiography of St Anthony Mary Claret. I read on St Anthony Mary Claret's Autobiography that he read all writings of the saints and lives of the saints he could get, and he became a saint by such reading and imitating the saints (from the spiritual reading). So spiritual reading begets saints. Oh and the broken links you mentioned are now fixed, you can check the books out.

 

Please don't mind the trivial details. Just take the books and go away happily. I use Android and it works fine for me. For Android there are a lot of alternatives for PDF and EPUB readers on Play Store. For PDF reader I use ComicScreen. For EPUB reader I use Skoob EPUB reader. Just look it up on Play Store. The site has complete collection of writings of the saints from A to Z to download in PDF and EPUB format. God Bless  

The broken links had been updated. You can try again. 
Try the "Saints' Books by Alphabetical Order (All)" menu and the mirror links. They still work.

Catholicpdfbooks [dot] blogspot [dot] com had the updated links.

Yes

I found a site that hosts saints' books in alphabetical order
catholic-ebooks [dot] blogspot [dot] com

I hope you can add the books to the saints books site.
