Delivering author specific content includes identifying author specific content with tags inserted into its metadata across multiple online resources and delivering updates about the author specific content to a user specified activity stream. A subset of the functions that are provided by the server and that are available based on the request may be identified. Advantageously, the coded information reader of the invention has small size, reliability and flexibility of use. The leakage across the bottom of the STI is eliminated by the simultaneous implantation of the well species at the interface thus raising the dopant level of the parasitic channel.
