Toolkit - Literature search

Today I started compiling an index page for literature search .

This is located in the Toolkits blog inside our Research Cooperative network (see subtab under the main Support tab in the main menu).

Each entry has a short introduction, and spans a different range of material.

They all have different search systems, so it is useful to try them to find the systems most useful for your own purposes.

Please comment here to recommend any online search systems that are not already listed.

Thanks.
