Reply To: Otzar HaCochma vs. HebrewBooks vs. Bar-Ilan

Thank you for the explanations.

Is more or less everything in Bar Ilan (as well as in HebrewBooks, Sefaria, DBS) also in Otzar Hachochma?

Is there any hashkafic issues wish Bar Ilan, considering it is produced by a secular university? What are the hashkafic concerns with Sefaria?

How does Sefaria, DBS and other similar offerings compare to the aforementioned?

On a technical note, I understand that some of the older versions of Otzar Hachochma or Bar Ilan were made available as an all-in-one complete on CDs with a one-time purchase, whereas the currently sold versions are accessed online with a subscription rather than having it all installed on your PC. Is that correct?
