It is possible, but very rare, to get Fortune I without bookshelves since the table goes up to level 8 with no bookshelves and Fortune I appears as low as level 3 for gold and level 7 for iron (diamond requires at least level 9 so you need at least one bookshelf. The calculator does not show the probabilities of individual enchantments for books but Fortune did not show up as a possible enchantment until level 12).
Do i need any bookshelves at all?

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
