In the past, a Logos recommended purchasing strategy was to hold off purchasing new volumes in a series that was part of the base package (e.g. commentaries), because Logos may include them for a very small price as part of a future version of that base package.
My recollection is that this strategy was advantageous from L3 to L4, but not from L4 to L5 (e.g. Latest NAC volumes and Ency. of Christianity were excluded from upgrade to L5). At least this was my experience.
Now, consider that from time to time Logos loses the ability to sell some resources or include them in base packages, such as those published by Moody and Baker, respectively.
A Logos salesperson says this purchasing strategy is still valid, but given foregoing, I’m thinking this is not such a good gamble anymore for important resources.
Your comments please.
