There are multiple approaches, none of them will cover everything I'm afraid. 1) separated databases + all titles can be tracked - only one db can be online, thus synching those two will always involve a bit of work, most likely via a USB-stick - no immediate possibility to print one list 2) custom collection categories+ one database, uploadable so synching would be easy. - only one copy of each title possible 3) tags Simply create tags "Main" and "Holiday" and assign them to the concerning titles + one database, uploadable so synching would be easy. - only one copy of each title possible For the "one copy"-Dilemma: you could manage those in 3) with simply assigning both tags, but that will screw with the numbers of discs. As for moving them from one location to another: you can either move them to the other DB/Collection for a permanent solution or loan them to users "Main" and "Holiday" for temporary assignment. cya, Mithi |
