TOC

Here is the final table of contents for Effective Perl Programming, 2nd Edition. The “Item” references in our blog entries refer to the items in the book.

We also have a map from the Item numbers in the first edition to those in the second, but we’ll have to do a little work to make those look nice for the blog.
