if appears as a footnote so the analyst calculate say, net income, if the firm had used FIFO instaed of LIFO as an accounting method

Dante, yes the LIFO reserve appears in the financial statement footnotes only if the company uses the LIFO method of inventory accounting. It can be used to calculate the value of the company's inventory account if it had used FIFO, rather than LIFO.
Inventory_F = Invetory_L + LIFO Reserve
Why does this matter?
LIFO is preferable from an income-statement perspective b/c COGS is more reflective of the current replacement cost of inventory. Conseqeuntly, gross margins are more accurate (and lower if replacement costs are rising, also resulting in lower taxes, hence the popularity of LIFO).
However, FIFO is superior from a balance-sheet perspective because old inventory is getting used first (and removed from the balance sheet), so what's left is the more recently acquired inventory which better reflects the inventory's true market value. This also explains why FIFO firms may overstate gross margins if invetory replacement costs are increasing and inventories are stable or increasing.
The LIFO Reserve gives you the best of both worlds: LIFO on the income statement while preventing the inventory account on the balance sheet from diverging too much from market values.
ZForce's post needs to be qualified further:
Yes, LIFO Reserve can be used indirectly in reaching net income calculations. It's used to convert the COGS of FIFO firms to the COGS of LIFO firms:
COGS_L = COGS_F + delta(LIFO Reserve)
Don't let those FIFO firms lead you to believe their margins are so stellar!
On a side-note, LIFO firms can get crafty with their gorss margins too. If they allow their inventories to begin depleting, the situation is called "LIFO Liquidation" and a bunch of old (probably cheaper) inventory will pass through the income statment into COGS, grossly overstating gross profit.
Finally, I think most people learn this stuff assuming that replacement costs are increasing and inventories are stable or rising (which is a good way to start), but don't consider how all of the relationships reverse if prices are declining and/or inventories are being depleted.
I'll wager CFAI goes straight for the jugular on these questions.

I'm waiting for my LII results (it'll be close), but as my post above demonstrates, months of therapy haven't let me forget the past... inventory accounting nightmares haunt me to this day!
