Less resource on iPad than on PC

Although its the policy of logos to make as many of your resources available to you on mobile, not all publishers oblige.

The good news is more resources are becoming available on our non pc devices every day. I have a similar size library and less than a year ago the difference in your two numbers would have been about 261, instead of 61. 

Thank you pastor James. 

From your experience, is there any way to know the missing resources on my iPad without going through the two lists in both devices at once?

The other item someone mentioned to me once is any Personal Books you may have... that's what the difference was for me.

I can download to my iPad or smartphone 6,957 out of 7,061 recources - 98.5% - quite good I would say.

v6 of those 104 resources not available remotely consists of one publisher-produced volume - The Works of Oswald Chambers. I believe a lot of the rest are resources I purchased a long time ago from the E4 Group, which abandoned Logos at least 5-6 years ago.

No. The best way would be to have a "mobile enabled" field in L5 but that doesn't exist (yet).
