To be fair, not all or even most of the suppression of the Apocrypha was active and intentional. Most of it was simply that they'd been judged to not fit in with the religion the council was building, for whatever reason (probable forgery, ill-regarded author, or simple lack of a discernible moral lesson), and that most of the preservation of literature was done by the church. There wasn't so much an organized hunting down of the things (though occasionally a pope or bishop or something would take it upon themselves to go a zealot on us) as a general apathy among the people maintaining the libraries. If you were a monk, would you spend a year of your time copying a decaying tome whose contents your society had deemed worthless, when there were thousands of competing volumes of actual worth that needed copying to avoid being lost to the ages? Me neither. I mean, copying a single book was sometimes a monk's entire life's work, that's a big investment.
So lighten up, it wasn't ill-intentioned. And most of the apocrypha are either crazy or pointless (in my own estimation as well as the church's), so meh anyway. Hell, I dunno how most of revelations didn't get thrown out as well, it's pretty whack too.
(Side note: would have been nice if more monks had thought books of math and engineering were worth the effort, all we got was the half-assed job the muslim translators did of preservation. Better than the complete absence of the technical books in europe, but still. Anyhow, if you're going to be mad at the church for losing books, be mad at them for those, not the useless apocrypha bullshit.)
