For up-to-date and historical S&P 500 p/e ratios use Bloomberg, available in Lippincott Library and Huntsman Hall.
For a table, type SPX hit the Index key, then type HE and hit GO
For a graph, type SPX hit the Index key, then type GE and hit GO

For historical S&P p/e data (back to 1967), come to the Lippincott Library Reference Desk and look at Standard and Poor's Analysts' Handbook HG4519 S772 RD.
