PDF Index Generator is a powerful indexing utility for generating the back of your book index and writing it to your book in (4) easy steps. PDF Index Generator parses your PDF, collects the index words and their location in the PDF, then writes the generated index to a PDF or a text file you specify. The main target for PDF Index Generator is to automate the process of generating the book index instead of doing the hard work manually.
I didn’t get to try this out, but I had it bookmarked. (UPM was very kind to do the indexing for me since the moment it needed to be done was also the moment that my father died.)
[Macworld has a great tip](http://www.macworld.com/article/1168311/shrink_preview_files_without_ruining_image_quality.html) on how to shrink Preview files without ruining image quality. Essentially, it entails navigating to:
and then copying the file `Reduce File Size.qfilter` to some place where you can edit it. No fear: it’s an XML file, which means you can produce multiple versions for different effects, making sure you give the versions different names so you can move them back into the `Filters` directory when you are done. (You will need to be able to authenticate to do so, just as you had to make a copy of the file elsewhere in order to work with it: Mac OS X does not want you editing its innards live.)
The parameters you are going to adjust are: Compression Quality and ImageSizeMax. The article has some good suggested values, which are a good place to start as you tweak things for your own benefit.
