As someone who started using tape backup in 1978 (sic) and first bought body armor in 1984 (sic), yeah, I hear you. And my personal anecdote is how multiple forms of backups saved my critical data from this: http://www.ancell-ent.com/1715_Rex_Ave_127B_Joplin/images/ http://www.ancell-ent.com/1715_Rex_Ave_127B_Joplin/images/ (rsync.net, since the disk backups in the bathroom got trashed). Fortunately haven't had to put body armor to real use. But between the way I prefer to use many computer books (multiple windows on a big screen), the ease of saving them to multiple backup sites (every time I buy digital media I upload copies to rsync.net and ironically Amazon's free (5GiB?) service, plus they're in my normal backup systems), how fast their content gets obsolete, and their lower price, I tend to buy them. But only for the perishable stuff, I get e.g. CS books in hard cover. As I noted elsewhere, you also want those physical shelves backed up by a good insurance policy, and for you I recommend USAA, my father started with them in the 50s, and especially due to tornadoes and the like we've had to make a lot of claims.
