Pending legislation is most easily found on the California Legislature's website. Somewhat confusingly, there are two different websites for legislative information: California Legislative Information (the newer site) and Official California Legislative Information (the older, and more useful, site). Both sites will have the text of bills. If you need other legislative documents, then you'll need to look at the Legislative Publications page of the Official California Legislative Information site.

History
The Assembly and Senate each produce a History showing the actions taken on each bill. Unlike the Journals, which are ordered by dates, the Histories are ordered by type of bill and then bill number.
