Any decent resources for studying compression algorithms?

I'm looking for any good resources - books, websites, papers, etc. - for information about the design of compression algorithms. Not how to implement specific codecs, but how compression algorithms are designed and how metrics can be developed to show effectiveness, how searching compressed data can work and the trade-offs between speed of compression/expansion vs. data size etc.

I need to design a compression codec for a specific type of data, but I need to make sure I consider all the basic areas of compression algorithm design.
