UPDATE FROM 23-FEB-2021: I have also added to my blog the ITRANS-Sanskrit version of all "Shree Varaha-Purana" 218 Chapters (searchable TXT-file, just 1.6 MB), please see THIS POST.
DOWNLOAD (SANSKRIT, PDF-SCAN, 103MB):
English annotation by Vishnudut1926: This Sanskrit edition is great, but the numeration of Adhyayas is rather tricky.
I have embedded numbers of Adhyayas right into Bookmarks (can be seen via "CTRL+B" in most pdf-viewers), so everybody can find the necessary Adhyaya in a second.
I am using this Sanskrit scan in conjunction with English translation of "Shree Varaha-Purana" by Motilal Banasirdass (this one).
Please note, that some discrepancies are possible (for example, Verse 53 in Sanskrit edition maybe Verse 56 in English edition and etc.), but both Sanskrit and English scans are quite similar, so both scans are fit to be studied in conjunction.
