I have read that the main branch is an affiliate of the Family History Library and it will loan items from it. I was curious of the process and
Thanks for your questions! Yes, the W. Dale Clark (Main) branch is an affiliate of the Family History Library (FamilySearch.org). FamilySearch has discontinued their microfilm lending program, however, so patrons can no longer order microfilms to be sent here or any other Family History Center. However, FamilySearch is rapidly digitizing their vast collection of microfilms and books. Many of their microfilms have already been digitized and are viewable online; some of those, because of restrictions set by the record owners, can only be viewed in a Family History Center or Library Affiliate (which includes the main branch of Omaha Public Library).
Looking at the catalog record for Taylor County deeds, I see that only the first reel of the grantor-grantee index has been digitized so far, so the deed books are not yet available. It is possible, though, to contact FamilySearch Support and request that a film be given priority for digitizing--there is information about that here.
The good news is that probate records for Taylor Co. have already been digitized, and you can actually view them on your home computer. You will note that only the first reel is indexed, but many or most of the digitized registers and ledgers will normally have their own index (in the original book). And the will books have also been digitized!
These do not appear to be restricted records (those are normally designated with a little key over the camera image), so you wouldn't have to come into the library or a Family History Center to view them (though of course we would welcome you!).
Records that do have to be viewed in the Main Library can be viewed on any library computer in the building, but not laptops.
I hope this answers your questions--feel free to call us in the genealogy department at 402-444-4826 if you are still wondering about anything!
