I've finally sorted out my library and tagged everything.
I have spotted several books and collections from way back that have been republished by Logos - is there a way to upgrade to the new logos books or do I have to re-buy the collections at the full price?
For example, I have the Wesley collection by Ages Software (1999) which is in the lbxlls format. Logos now covers the same resources in logos4 format. I presume the former, while still readable in the logos software, is neither supported by logos and will not be updated with logos in text tagging etc.
