I already have a PDF of 812 pages in Hindi language but I find that the language/words used are sometimes a bit tough to understand. I have visited some sites which have downloadable versions in English as well but there it seems to be a bit shortened. Through this site I came to know about Sacred-texts, etc., sites which have authentic versions and verse by verse translation so just wanted to know if any such translation is present for Shiva Purana. If yes then please provide me the links.
As I far as I know, the only unabridged translation of the Shiva Purana is the four-volume translation published by Motilal Banarsidass. Here is a link to the table of conents.
The translation is available online on DSpace, the digital repository of the West Bengal Public Library Network. Here are the links to all four volumes:
Note that DSpace breaks each book up into 80-page chunks.
Unabridged Shiva Maha Purana is now available in text searchable format on archive.org. This is the same Motilal Banarsidas Edition. Download PDF with text format.
if you want to read Shiva Maha Purana in Sanskrit with English translation, read Shiva Purana on Indian Scriptures. This version is not text searchable. BTW, Indianscriptures is very good site if you want to read scriptures in both Sanskrit and English.
Additionally, if you are interested you can read complete Linga Maha Purana in text searchable format there.
Visit Indian Scriptures, if you want read in both Sanskrit and English.
The following is the full English translation of the Shiva Purana including an interwoven glossary. It contains over 600,000 words and starts with a Mahatmya, extolling the greatness of the Shiva-purana. It cross-references the Sanskrit original text and includes romanized orginal names using the IAST transliteration scheme.
