Also, a good version control system is very helpful for this task. I recommend Subversion with ViewVC (both Free). With ViewVC you can browse the code in a web browser, with side-by-side, color-coded diffs. If you can describe the syntax of the file, you may be able to adapt a tool like LXR: http://lxr.linux.no/ I find these web-based code broswers very convenient to use. When writing notes about what you are doing, you can insert URLs to the relevant code section. (I write my notes on an internal wiki, but even MS-Word lets you insert hyperlinks.) Also, the code can be accessed from any computer in the organization, which may or may not be helpful to you.
