(this opinion is already posted in LM317 thread).
Regarding the datasheets, my experience is: trying to find out the ones from the manufacturers' website, especially the original inventor-manufacturer, for example LMxxxx ICs from Nationnal Semiconductor website, Txxxxx from TI, Mxxxx from ONsemi, Freescal (formerly Motorola semiconductors), etc, ...
The datasheets from manufacturers are always free, and usually contain the most fully set of info like technical characteristics, application hints, circuit examples, ... while the datasheets from any other sources, especially free ones, only contain the most essential info as technical characteristics.
It is also easy to find out the datasheets from manufacturers' website, just "google" the keyword and then look for the link from manufacturer.
Only looking for the datasheets from any free sources, like datasheetarchive.com in the worst situation.
Hope that may help.
